mottled and canoing leaves on young veg

Hello,

I actually posted in a different thread, not knowing this was here on the forum. My apologies.

I am having a strange issue that I can't figure out with one of my GSC plants. It has had this strange, bumpy mottling since it sprouted and I keep thinking it will grow out of it, but it's in the new growth.

I am growing in soil with FFHF- I amended that with some worm castings, humus, perlite, and a bit of recharge. The soil is from the same batch as my other plants.
Light is currently a 100W LED. Plenty of distance and had it dimed down pretty low to around 100 UMOL when they were little. I have not used any additional nutes. I tested the soil in a slurry test and came up with 6.2. I water with well water that is pretty balanced, but ph it down into the low 6 area.

Started the plants in peat pellets and transferred to 1 gallon fabric pots. I started watering a bit lightly to help walk them through the bigger pots. Initially i thought possibly some water stress, though now I don't think so. I have been watering more thoroughly and letting them dry before re-watering for 2 cycles now and am still seeing the same issue. I used some Recharge, thinking there was some root stuff going on, but haven't seen much of a difference.

I am starting to think it could be some weird genetic thing with this plant. It is a little bit stunted, but seems to be growing through it kind of ok. My other GSC is more compact with normal leaves and coloring, etc. This one is a bit taller with more space between nodes.

Being that I have only 3 plants, I'm gonna keep her(unless it turns out to be some kind of virus or something) but I would love to hear anyone's thoughts on what the heck is going on!

What is your environment specs ? Rh , temps ? What’s the light distance ? Def looks like heat stress . ? Do you have good air flow ?

I have kept temps mostly in low 70's. Humidity was kept higher as they were young(up to 70%), but now is at around 50%. Fan blowing gently on plants and suction fan to remove excess heat(mostly off or at low). The plants were generally 24-28" away from light, which was pretty low.

I have also put this plant slightly off to the side of the light. The other 2 started at the same time are showing no signs of light or heat stress. The thing that's weird is that I'm seeing this in new growth as well and I have changed all of those parameters, and even the ones I changed seemed to be perfectly in spec for what the plants should have been getting

And you could be correct with the genetics thing if you have others that don’t show the same stresses . I have a super glue that looks like yours , just not as bad . Others , perfectly fine .

Also with led lights you want your temps to be in the low to mid 80s . Something to do with the rate of the plant transpiring .

I hadn’t heard that about the temps.
It’s hard to get solid info. The internet is like an insane library where you have to really figure out how to intake info. I’ll look into that.
I was pretty psyched with how dialed in I was able to get my setup with minimal components(less chance of failure). It would be harder for me to hit mid 80’s. I thought that was only when you were really pumping co2

I actually have ir in this led. I will try raising the temp a little bit. Quick reading that I will follow up on.
In any case, I don’t think there has been anything to create he’s stress, especially for the last week or so

I didn’t believe the whole led lighting temp thing either , but than I looked it up and found various sites concurring this . my growth picked up when I put my temps at 83 instead of 73 lol I do also dial everything down at night by 10 on rh and temp. The only time I have read that co2 is required is if you are cranking out some serious wattage in your tent . Don’t quote me on that tho . Lol

When I say heat stress I mean more or less by the light , not temps . And my light is 39 inches and at 50 percent power and is still cooking my super glue and yet my others are perfectly fine . Could be the genetics . I’m new as well . Sharing experiences and readings .

My system has a temp control that runs the heater and fan. I wish i had gotten a humidity/temp but didn't know it at the time, and don't want to buy more stuff right now. My tent is in a shed and the shed has a small wall heater. I've been trying not to use the wall heater as much as it uses a lot of amperage. My little tent heater barely pulls any juice and is able to keep the tent relatively warm. I actually had it in the low 80's for a bit, but pulled it back down.
I'm gonna try to raise it a bit into the high 70's to low 80's.

Regarding the light, with LED's, I would imagine it would be hard to get heat stress unless they are right on top of the plants. I've read much more about bleaching and so forth(assuming the temps aren't too hot). I have a PAR meter and outside of needing to solidify what different stages need(again lots of conflicting info) I don't think there has been a time when there was too much light on the plants. I have been pretty conservative to this point. I have actually raised the light to around 300 in the last couple of days as the plants enter their Veg, and they seem to be responding well.

Part of this grow is experimenting with a lot of the technology that wasn't around when I used to do this. I never had a light meter. Never used LED lights. I want to figure out a number of things, including light balance for different stages, accounting for different types of lights, etc.

It’s gotta be a genetics things . And yeah I have humidity and temp controllers too . They’re absolutely a godsend . I literally do nothing but add water to my humidifier and change the temps by 10 on a night to morning basis . I wouldn’t dwell too hard on exact numbers and stuff . A lot of the people on here seem to say keep it simple . No need for par meters and stuff . You can also download a lux meter on your phone and save yourself some money .

I dig the par meter. Cool to see for myself how lights actually perform. I have a vivosun 200 for instance that has crazy light. The numbers I get are in line with what they say(lots of debate about the specs on those chinese lights)
So far I’m able To get away with the temp controller and keep humidity where I want it.
We will see what happens when we get into flower
