Heat stress or ?

[Mellaya]

Hi guys, my seedling is almost 2 weeks old now. I noticed some odd behaviour from him last few days his leaves and nodes seems to be going up everyday as if they have an erection. I did read about it on few forums information seems contradicting itself. It's either a good sign or a sign of heat stress. I can't see any clawing or leaves colour changes. A bit information

Not as good new growth looks a bit retarded now all twisted the only thing I changed is done some LST and started foliar spray with seaweed in it. Can't diagnose but I'll cut the foliar feeding for now see if it recovers. Also it's showing sex now on day 20 I'd like to veg her for a bit longer she's really tiny still

I've never seen the need for foliar spraying
It's true that I start feeding them as soon as humanly possible, and before that all they need is water, warmth and humidity.
Also I try to keep it as simple as possible

Looks like foliar feed was the problem they recovered today and looking lovely
