Help a guy and his girls out :)

Hey guys new to this forum and first time growing indoor in coco, these girls where cloned and rooted in a Aeroponic system then transplanted into coco/perlite mix fed a 2 part veg solution at half strength with a little bit of rooting hormone to help them get established in the medium, they got a little bit light burnt when in the Cloner on the last day (I stupidly turned the light up a little before going to work and got home to them not so happy ) they recovered well and didn’t seem to fussed, have been under my LED 450w full spectrum at about 30% strength and the light is about 800mm away from their tops, they have developed a little rusting and twisting on the old growth but all new growth actually looks really healthy and lush, any idea welcome please!

Want to add in that I did not do a calmag soak before hand either and have read that coco can hold onto magnesium a lot, I have read a lot of threads about diagnosing plant issues but are finding it hard to pin one thing as all the deficiencies have very similar visual effects to the leaves

I really do not understand how low light intensity would have caused issues like this but whatever. I would let the light just be how it is for now, mix sufficient amount of calmag solution around 1,4 EC with adjusted pH to 6,0 and make a nice and proper drench, than refeed with ballanced food at 1,2 EC. Assuming you are using tap at some reasonable initial EC, you can use that water straight from faucet with any worry about dechlorination bullsha. I believe your issue is calcium related. Also keep your temperature up to help with proper transpiration.

I didn’t say it was the cause
He is changing several things at once
But I also don’t see how any light at 30% power 31 inches away is something you would want to leave that way?
I’ll admit I’m new to LED’s so how does that work?

I'm leaning toward planting stress. They just went from a water based growing style to your coco. Give them some time and hit them with some microbes.

Coco locks up and retains both calcium and magnesium, to the point that it is almost like feeding the medium. I just use my tap, it comes out at 350 and 200 of it is calcium. I'd get a water quality report from your utility company so you know what exactly is in it.

Also, your light distance... if the plant isn't stressing you can go closer. Listen to her she'll tell you what she needs. Those leaves don't look like they are trying to hide from the light, they almost look like the humidity is too low. I keep my lights at 4 and 4.5 ft. off the floor, running at around 4-600 watts (40-60%) and they are fine. Both of my lights are true 1000w leds (not Amazon's "output equivalent")

the light will slowly be dropped over the next couple days I was worried that to much intense light while they try to get comfy in the coco would do them no good , turned the light up to 40% this morning and dropped it a little will check after work and if they aren’t stressing to much I’ll drop it a little more, my temps have been good but they did go a couple days at about 40% RH humidity is under control now and is stable at around 60-67% temps have been stable at 23-25 since transplant, they have microbes they where also added into the soak before transplanting them, will be going into 18L fabrics when they out grow these pots and will add some neem shell into there new mix as well, I will do some calmag in with next feed and see how they respond. Do you recommend giving a bigger dose than recommended for the calmag? Since the coco will soak some of it up?

Exhaust fan is not running at the moment as it’s pulling all the humidity out of the tent, there are running fans in the tent with vents open and I can feel fresh air entering then tent through them, will turn in the exhaust when they are bigger and taking more water and humidity become higher because of it

I dont think its the light. Im not sure exactly what it is but I doubt its light burn from an LED so you can probably scratch that. In a couple of the pictures the light color in between the veins could indicate cal mag needed.

I know it’s not light burn, in my post I said they suffered some light burn while they where propagating under a 6500k, calmag seems to be everyone’s guess so going to go with that, would I be including calmag into my next feed or just do a calmag flush with phed water and no nutes

I would just give them some water with some calmag now. Not a ton just the recommended dosage. They should be fine. I feed calmag every feed. I believe I read somewhere that cannabis grown under LED needs more Calmag <(I just heard about this so Im not sure if it is true or false, Im still doing reasearch on this)

After including calmag with my feeds and lowering the light the plants have come back with a vengeance looking super healthy imo just some update photos for the guys who helped me out, again thanks for all the reply’s ! Also began some topping and lst in some of them topped a week ago and the lst was just tonight so hanging out to see how they respond !
