Leaf Curl?

[FullKeel]

Hi, New member, new grower.

Things seem to be going well, but I have some leaf curl on a couple of young plants.
Plantes were srpouted from seed, Freedom 35 strain.
Thought maybe due to nutes: Medium is a 50/50 mix of ProMix and Foxfarm Oringinal.
A dip in clonex, root excelurator soltion when needed, ph 6.5...but other plants treated the same way did not have leaf curl.
Thought maybe it could be heat stress or being too close to lights, but again, other plants in same situatiuon seem to be fine.
Room temp gets up to 85 plus..ac is on the way.
Plants are under an 8 bulb t5, about 8 inches above canopy.

I have since placed them under a fixture that sits about 24" above with cooler temp of about 80d.

Any insight would be greatly appreciated.
Thanks

FORGOT to mention age of plant.
I placed germinated seed in red cup about two weeks ago and transplanted in black 5" pot, as shown in pic, 4 days ago.

Thanks again.

I have a strain called Tangarine dream. I have learned that if it is too dry. or too hot or too anything... it will taco...

Is a post i made a while ago asking the kind folks of icmag what is going on. If you would like to read thru and join the conversation you are more than welcome. feel free to post pics. you may get feedback you are looking for

About the tacoing or curling. be patient watch closely and see. is it heat? is it whats in your soil? is it a calmag deficiency? is it the humidity levels. watch and experiment slowly and carefully and you will figure out the issue at hand.

Until another time

Have the same symptoms, only in flower, due to lack of potassium. Locked it somehow, see my post little below. You can up potassium, but usually that is not a good idea. Maybe you have too much nitrogen, which could block K uptake. Read my post, some good advice and videos....
Sorry, can not put link, on my phone now

Thank you both!!! I have climate control unit on way bc temps are a little high humidity is also high
75%..if i correct temp/rh and there is still a problem, i will then look at possible nute defic.
Cand wait to read provided links. Thanks again!

I had a heat issue early on & symptoms looked the same as your pic.
BTW, the extreme left hand number on your thermometer says 102.3 F ~ is that your "high" temp ?

I'm pretty sure that's your answer.

I had the same issue, but just with the lower leafs (one fingered). Should be due to low humidity
