Seeds put into wet papertowel.

10/19/21
Ran .4ec of nutrient solution through the coco until Inflow ec matched outflow ec. Placed seeds into coco.
ec=.4 ph=5.8

10/20/21
All seeds break coco.

10/23/21
First watering
Inflow: .4ec 5.8ph
Outflow: .4ec 5.7ph

10/26/21
I noticed slight light green color on new growth so I bumped the nutes to 1.0ec. The picture is from after watering today.
Inflow: 1.0ec 5.8ph
Outflow: .8ec 5.7ph

Sounds like a cool grow!

I can dig it. After playing the bottle game for years, I'm now an A&B only type of guy, though I use Canna

 

[Moshmen]

Only one bottle here pure blend pro grow - I’m in to watch

The bottle game is so much fun and costs so much that this last run it was just A&B, Silica, UC Roots, Cal Mag. One of the best I have ever run!!

Day 11
I noticed some purple coloration on the leaves. My light is 36-40 inches away from the plants. Running it at 200 watts. I can adjust the spectrum on the SolarSytem 550 currently running 60% white 60% blue and 30% red. Not sure if that has anything to do with the coloring or if the light is too close at 36-40 inches. Also my last watering was at 1.0ec 5.8ph, 5ml Veg A, 5ml Veg B. Any feedback is greatly appreciated. Thanks dudes!

Day 11
Lights out.
Finally able to get the humidity up.
Trying to stay within an acceptable vpd range.
Raised the light a little bit as well.

Day 12
One of 7 has developed a yellow spot on the 3rd leaf set down from the top. Anyone have any idea what could cause it(pic below)? Everything else is looking okay. I did notice on a couple of the plants the center of the leaf almost domed out, it can be pushed in or out. Not sure what causes that. Will deff be back filling the ones that stretched come transplant time. Thanks dudes!

Sounds like your temos are cold to me.

I can see the top of the coco is drying and you don't want that. If there is one thing I can convince you of please let it be that coco is no soil and should not dry.

Have a read here.

Leaf may just be some nutrient solution dripped on it.

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

Day 13
Really appreciate the feedback Eric and Aqua!! Thanks a bunch I will deff keep them wet and keep an eye out for any further symptoms. Just got done watering them today and they deff loved it. Temp and humidity are up as well.
Inflow: 1.2ec ph 5.8
Outflow: 1.0ec ph 5.7

Day 13
Do you guys suggest doing anything about the color on these? They seem a little lighter than they should be. All 7 are this color. Not sure if it's anything to worry about or not. Could it be from not having kept them as wet as I should have. I know Aqua mentioned not to let the top layer dry out. Thanks dudes!

 

[urijah710420]

Thanks Eric! The 3rd photo a flash was used. Pic 1(flash)-2 (no flash) are the same plant and Pic 3(flash) and 4(no flash) are the same plant. You're right using a camera phone deff has it's limitations, I figured might as well include flash and no flash to see if yall could see any issues.

 

[urijah710420]

Forgot to answer your question about temps. Sitting right at 79-80 currently. Humidity is at 60.

 

[urijah710420]

Quick question. For the last 14 days I was running my veg tent without an exhaust going just had the intakes at the bottom open(passive) with a filter over the bottom holes on each side. Both holes are 12 inches with filters over them. What I'm wondering is could that have caused too little c02 in the tent, possibly causing issues? I've got the exhaust hooked up now and the plants deff seem to like the fresh air coming in. I was thinking since they were so small I was going to set up the exhaust next week but then was thinking maybe it was causing low c02, possibly causing the lighter color i was seeing. Either way the exhaust is hooked up and ducting the stale air out of the top of the tent. If they were affected by low c02 as seedlings could it affect them later in flowering? Or since I fixed the issues, i shouldnt worry about it? Thanks dudes!

Day 15
Thanks to aquaman for answering the above question! All plants were watered today. I will be sticking to the aquaman guide to watering coco linked above. I Will be keeping them 90% saturated for the most part. Bumped my base nutes today from 6ml's to 7ml's the ec went from 1.2 to 1.4. Noticed one plant was a little droopy today before I watered(circled in red), guessing it could be because I wasn't watering enough as aqua mentioned. Also noticed on my smalest plant one of the leaves grew out a little mutated(circled in red). Anything to worry about there? Here is today after watering all 7:
Inflow: 1.4ec 5.8ph
Outflow:1.3ec 5.6-5.7

 

[Madmax]

Id go a little easy on the nutes bro..they will grow with half that at this stage..hell im only feeding 510ppm and 560ppm in flower ..

 

[urijah710420]

Thanks madmax! Next watering I will drop it back down to 1.0ec and stay steady there. I was thinking maybe the lighter color was from them needing more since I'm only feeding base nutes but since I plan to keep it at 90% saturated as aqua suggested less is prolly more when doing multi feeds. Does anyone here watch VaderOG (ocean grown seeds)on youtube? He uses Canna Coco with Canna nutes. I noticed him starting seeds at 1.4 ec which seemed crazy high but I guess it works for him

Day 16
Reset all cups from 1.4 back to 1.0ec 5.8ph. Will be using the aquaman feed method from here on out. To start every 4hrs I will run 30ml's thru each 18oz cup to make sure it stays 90% saturated. I will be checking the run off and adjust the time of feed depending on the run off numbers. Does anyone know whats going on with my smallest plant? The issue is circled in red. Almost like the leaf didn't grow out fully ? Mutation or something else Here they are today:

 

[Madmax]

When you reduce the feed from feeding high the runoff will tend to be over what your feeding it so dont worry too much when you see it..it will settle after a c few feeds.

They are looking good mate..
