Hey all! Decided to start a new thread since there’s so much that is new. Thanks to all the people that helped me out in the old threads!! Thanks a ton! I’ll go back and link this one for you guys.

Got a CMH 315 light, a 6in. online fan and carbon filter. And tried out coco. Using a random bagseed from years ago. Showed pre-flowed weeks ago.

Doing a push-through with the carbon filter. Still keeps a strong vacuum on the doors and such, so SHOULD do it’s job. It’s a big 6in Phat Filter. It says it works either way in the instructions lol. My nose for the herb sucks so I’ll have to have someone else tell me. Definitely get blasted in the face with the smell when i open both doors and not before that. Which leads me to think the filter is working wonderfully. Used like 5 layers of gorilla tape on the gaps/seams of the fan.

The main cabinet is 3ft wide, about 22in deep, and 5ish feet high.

Have the main single-chamber cabinet, and a smaller multi-chamber cabinet going currently. In the main chamber there is one freakin beast growing in straight Canna CoCo using canna nutes with some added Silica and some CalMag. She drinks 3 gallons of water every other day, hand fed. Usually feed her (per gal) the A+B at 10ml, with 8ml of Rhizotonic, 4ml of Silica Blast, 3ml of CalMag, and 10 ml of Cannazym. Comes out to like 760ppm. My tap is about 115ppm. Always pH to 5.8-5.9.... it stays much greener than at 6.0.

Tried going down to 8ml/gal of the A+B, but growth slowed and she got lighter green so upped it back to 10ml/gal. Gave her 11ml/gal last watering and she seemed to like it. Been keeping all the other nutes at the same dose.

Temps stay between 68-81*

She’s been vegging since 8/21, so about 10 weeks.

Have I ovengrown the cabinet? Lol! I think I’ll be able to fit her in here with some finessing. Need to flower NOW though! Have plenty of air circulation to help out on powdery mildew and such.

Something weird - on the last watering I looked closely at the runoff. I could see hundreds of tiny little springtails. Supposedly it’s a sign of a healthy symbiotic relationship going on in the roots? The plant is booming. In my opinion there’s been about no deficiencies or yellowing, even down below the canopy where it’s not getting much/any light. So I haven’t been doing much thinning out/pruning besides the little useless shoots trying to start way at the bottom. She just keeps chugging along and growing. Took lots of clones!!!

Any advice/tips? Anything/everything is appreciated!

Some pics of the lovely lady!

That last pic is fucking awesome,
Not to discourage you but 2 things are going on here.Either A you took the pics as soon as the lights came on and you had a cold room or B your plants are a little overwatered.Not enough oxygen to the roots.They have the tell tale classic sign of overwatered.You might need to back off the watering a little and let them dry out.Trust me man plants can go a while without water and will look healthy as shit.I have a few moms i water like once every 2 weeks and they look healthy as shit.Otherwise eveything looks good.

Thanks for the reply! It was right when the lights came on, plus I had just done a shit ton of LST tucking and weaving the branches.

The room gets down to 66-67 sometimes with lights off. Usually try to keep it above 70 with lights off. Think that could have an effect?

Could be slightly overwatering though too. Been giving her 3 gallons of nutes every other day. It’s in 100% coco. No plain watering or flushing or anything. Get lots of runoff, probably about a gallon. So kind of a mini flush? I let it go 3 days this last time and she got droopy as hell. Whoops! She’s all recovered and growing again now. Took just a few hours to recover!

You let the moms go 2 weeks between waterings in coco or soil? That would be nice!

The big gal is in about a 6 gallon pot. It’s 12in x 12in x 12in

Just did more weaving to keep everything even. Here’s a couple pics as she sits now.

The two sitting next to her are in SuperSoil in 3 gallon pots. Hoping to uppot them one more time before beginning flowering. Or might switch them out with something in the veg chamber

Here is the cabinet with the updates and odor control figured out

Trimmed her up a little bit underneath. Still have more to do but I’ll see how much it grows after thinning all this crap out. And munched on some sour candy.

Just another tip but in addition to a bit too often watering the nutes are a bit too strong.

It will get worse over time if not corrected.

Thick ribbed droopy leaves with tip burn are a sure sign of both.

Thanks for the reply!

I really can’t wait any longer for watering (I’ve tried lol) - I’ve been going 2 days. If I go closer to 3 then the pot gets so light I can just pick it up with a couple fingers and the plant wilts really bad. It’s in a big 6 gal pot too. She was transplanted from a 3 gal about 3 weeks ago. Any advice on extending the watering next time or helping it this time? It’s 100% CoCo - no perlite or anything added. I’ve read you want to be watering every day by the end of flowering in CoCo. Wrong/right/does it matter?

I’ll go back to A+B at 9-10ml instead of 11ml/gal. See how she likes it. I’ve noticed the thick ribbed leaves you mention on a couple of the plants. I’ll post a pic below to confirm.

Been feeding with 8ml of Rhizotonic, 10ml of Cannazym, 3ml Calmag, and 4ml of Silica. Always ph’d to 6.8-6.9. Silica added first, then CalMag, then base nutes, then addititives. 3 gallons every other day with a good amount of runoff. The pot gets real dry and try to catch it just before she starts to show signs of wilting

The pic with the bigass leaf with some tip burn and the “extra” leaf deformity - it came from the very bottom/underside of the canopy if that makes a difference. It wasn’t getting any light and looked to me like the plant started to kill it off. But I’m not sure. It wasn’t getting any light way down there so I plucked it off

I don't grow in coco but too dry is also bad. The ec rises as the pots dry out too much.

I also don't use any additives. You are putting a lot of stuff in there. I would reduce things more than 1 ml.

The plants only need NPK and micro nutrients. And cal mag to keep the coco charged maybe.

Sorry I can't help more.

Never let coco dry out like soil type mediums. Also, iirc, coco needs feeding daily. Coco needs a 5.8ph to be optimal



The reason for the crinkle may be from a hot spot created by your hood, and the uva-uvb drom the cmh light.

I reduced everything like you said, that sounded like a good idea. She responded well! The new growth isn’t as rigid/lumpy looking as the older stuff. I fed Canna parts A+B at 9ml. It came out to 720ppm and pH 6.8, didn’t even have to mess with the pH! 8ml/gal of the base nutes seems a little light. I think 9ml is perfect for right now. Thanks!

Been keeping it at 5.8, sometimes 5.9 so pH should be in check. It usually comes out to 5.8 without having to adjust the pH. Gotta love that! The feeding schedule is getting closer to 36 hours now. I’ve been waiting until it gets almost dry. Still very slightly moist if I stick a finger down in there. She goes KA-boom after every feeding. I’m going to experiment with other watering schedules with the next round of plants.

Haven’t thought about the hot spot theory. They are closer relative to what I’ve been reading. Most people say 12-20 inches. Hopefully that uva/uvb will lead to extra trichome/terpine production in flowering!

Can see roots poking all out of the bottom of the pot. Cleaned up more underneath the canopy. Going to do one more “tuck/weave” and then send her off into flowering in a few days! Yay! Counted like 68 tips earlier today

Here are a couple pictures from tonight. The color is kind of off because the pictures are taken under the CMH. I’ll take more under some regular CFL light tomorrow or something.

She STINKS!! haha I get blasted every time I open the cabinet. If you jerk off the stem for a few seconds and then take a whiff of your fingertips then smell like old ass dirty socks! Makes ya want to gag

I looked at my notebook, and she’s been vegging for close to 12 weeks now! Lol old gal. Check out the main stalk! Barky

And don’t mind the droopy plants on the right. They were transplanted about a week ago and was letting the soil get REAL dry before watering to make those roots go searching. They were watered about an hour before the pics. They’re in SuperSoil

How much foliage would you guys take off? A shit ton? Or just remove the stuff that is causing shadows on new growth?

I’m leaning towards cleaning up everything 6in. below the scrog net and taking off like 80% of the underdeveloped shoots that won’t make it to the very top

Update time! She’s getting a feeding of 3ml Silica, 3ml calmag, 9ml Canna A+B, 7ml Rhizotonic, and 8ml Cannazym. pH at 5.8. She’ll drink 3 gallons in a day and a half now. I usually water till about 30% runoff (about a gallon)

Going to flip over to 12/12 in a few days. At that time I’ll add in Cannaboost.

Did a heavy defoliation yesterday. At that time I also took about 90% of the branches out of the ScrOG and re-wove them all. Only broke a couple small ones! Lol

Hope I didn’t take off too much foliage!
How’d I do/how’s it look? I cleaned up underneath the canopy, removed about 2/3 of the fan leaves, and took off any underdeveloped undergrowth/small shoots. Took a few hours from start to finish. Don’t know how I got her to fit back into the trellis lol

Hoping for at least 4oz off of her - is that realistic? Better be from all this work!

On to the pictures! The first few pictures are from before the scrog trim

Day 2 of 12/12.. not much besides a little stretch going on. The new tops were slightly light green from so much new growth! She responded well to being tied down and thinned out. Tons of new growth!

Also counted the veg days today... she was vegging for 93 days! She’s stinky already

Gave her a regular veg feeding yesterday. Is it a good idea to start adding Cannaboost now or should it be started after the stretch is over? Planning on adding PK13/14 at week 3 @4ml/gal for the whole week and again at week 5 or 6 (trying to time it about 21 days before harvest) add pk13/14 again for another week. And that’s about it.

I’ve heard foliar feeding the Canna boost is great. Makes them frost up hard. Just don’t want to do it TOO late into flowering I guess? Maybe just the first 4-5 weeks after the flip?

Planning to continue the SCROG tying/bending/weaving for the first 7-10 days of 12/12

Currently feeding canna a+b at 9ml/gal along with 3ml of calmag, 3ml of silica blast, 8ml of rhizotonic, and 10ml of Cannazym. The ppm for the last feed was about 680. Always ph to 5.8. Was feeding up to 780ppm with 11ml/gal of a+b.... seeing how she likes the weaker feedings and will ramp it back up slightly when the buds are fattening up. She looked a little over fed before. Trying to learn to read the plant.

I'd say that as long as you keep her happy during flowering then 4 ounces is definitely obtainable. Seeing as you're not familiar with the strain it's hard to know what kind of a yielder it will be but just looking at it I'd say there's a good chance you'll get some nice fat buds on it.

That being said don't count on it. Chickens before they hatch and all that.

Sweet! We shall see how it goes. Have never vegged out a plant this long. I’ll make sure to post updates through flowering.

Still not sure when to add the Cannaboost. Once pistils are popping out everywhere? So sometime between week 1-3 depending on strain? Like once they stop the stretch and go into full flowering? Then add pk 13/14 around week 5-6 (approximately 21 days before harvest)? Or what? There’s hardly anything out there with actual answers lol

Here’s some pics from day 7 of 12/12. Got pistils coming out from everywhere and she is stretching like crazy!
