1000W - Coco/Perlite - Autopot - SBC#26, Permanent Marker, Vitamin Z, La Bomba

[legoal]

Hello, I just wanted to post my first ever grow and maybe learn from more experienced guys here along the way.

My Grow tent and what is inside:
Tent: 5x5
LED: 1000w Kingbrite P55 LM301h Evo with Osamr 660nm and 730nm
Exhaust fan: AC Infinity Cloudline Pro T8
Humidifier: AC Infinity Cloudforge T7
Oscilating fans: 5x5 Arctic P14 PWM PST ( I need help with the placement, i dont like it)

On the 20th of february i transplanted the first 3 SBC and 2 Permanent markers.
This is them, after 24 hours and a feeding of roughly 1.1 EC with 30% run off.
They are in roughly 3 litre pots with 70/30 coco perlite.

This is 24 hours after the transplant of 4x La bomba from Compound and 3x Vitamin Z from grounded genetics.

Here wer have them 7 and 5 days after transplanting them.

The same after 14 and 12 days, here they look really stunted. The SBC's and PM's look fine but really crispy i guess.

Ive fed them 1x around 2hrs after lights on every day, there were 2 days where I fed them twice, but i think they didnt like it.
I have increased the ec gradually to 1.9 today. The run off ec has been very low every time, thats why i have been going higher.

Current environment is arounc 23°C (73F) and around 61% stable humidity.
I turned down the light today from 600-700 ppfd across canopy to 450-550.
What else could be possible for the stunted growth of the newer clones and the crispyness of the older ones?

Looks like one hell of a nice setup, nice and clean too.... Best of luck !

How far from the light are those? Did the clones have decent roots when you transplanted them? I allow my clones to get almost root bound before i transplant them and i don't feed them for at least 2wks.

Yes, the lights are to close, that is the curling of the leaves. The first 2 or 3 weeks of a freshly rooted clones is centered on root growth, let your coco almost dry before watering again. This will encourage root growth. Nice, well planned grow area.

I'm only on my 4th grow, but it seems to me that the more you feed them, the faster they will grow - like weeds! Accordingly, I just set my timer to feed every 2 hours, with a bit of runoff each feeding. (Less at night). If they have the right conditions (light, humidity, temp, nutes), they just grow amazingly fast. I like that I can get away with feeding every 2 hours in coco without drowning roots. I germinated seeds, put them in Jiffy pots, and put the Jiffy pots into red solo cups filled with coco coir. (I use a buffered mix). I watered by hand, sparingly, for a week to get a good set of roots without drowning them. After a week, I transplanted from solo cups to 3.5 gallon airpots, with every-2-hour watering. Roots are growing out of the airpots at the bottom already at 2 weeks. At 3 weeks in the airpots the stems are the size of my thumb, and I turned the lights from 18/6 to 12/12.

I have an Apogee meter than shows 550 ppfd at the plants, with a 600w light at maximum power. I raised the light until I got 550 ppfd, and I'll continue raising it as the plant stretches, and if I run out of space I'll reduce power. I have about 3 feet of space I can raise my light. (4x4x9 Gorilla Grow tent with height extension).

As mentioned, you have some leaf tacoing due to strong light. Hopefully you can reduce the power because it doesn't look like you can raise the light any. Do you have a light meter? Without one you're just guessing at strength, until your plants burn.

Hello guys, just wanted to post my update here.

On the 9th of march they finally got transplanted in to the 20l autopots.
This pic is them right after transplant and a little defoliation.

Yesterday I topped 2 of the SBC's, supercropped some and LST every single one of them to get them almost on the same height.
This is what they look like today - im happy with the result :)

Since transplant they got 2 feedings, right after and yesterday after the training.
Ive been getting yellow leave tips one some of the plants. I think its not nutrient burn. The SBC 26 is said to be able to withstand a lot of ferts. Another thing that makes me think its not nutrient burn, is the fact that this started happening only on the bigger plants and not on the smaller ones. I think this might have been more of a deficiency thand a nutrient burn.

I have fed them the following nutes yesterday.

Ive used roughly these amounts 4x for roundabout 45l osmosis water. I upped cal+mag by roughly 10% and got a EC of 1.9 and ph 5.9 and fed them until ive had runoff. lets see how they develop the next few days.

When do you think can i start the autopots and the airdomes? im already tired of hand feeding them lmafo - i should have bought a drip table for sure.

UPDATE TIME!!

As of today the ladies are on Day 16 of Flower.

For the circulating air i have 25 Arctic P14 PWM PST in 5x5 rows. 5 On top of the lamp, 2 rows blowing on the canopy in front of each other, cou can only see one on the pic. 2x5 Below the canopy + a 200mm Intake fan blowing air frow below as well.

The Humidity in the room with the tent stays between 35-40% but i am struggling to get the tent below 50 consistently. Currently it stays between 50-58 day+night. What else can i improve, to get the humidity below 50%?

I have defoliated 2 days ago and it has been a great improvement, should i defoliate even more? Ive got new under canopy lights on the way, so I wouldnt like to defoliate too much but I am open for any kind of suggestion!

That canopy

Leaves at the bottom, especially large fan leaves can likely get chopped if they are not getting much or any light. Can you snap a couple of pictures from underneath?

I have to tell you, that looks pretty sweet!

Will post some from below tomorrow!

Here are the pics from below. to be honest i did not think the light would still even penetrate this much. nether the less im gonna do another good defol and get rid of the thin sucker branches.
