Lack of Nitrogen? Hot temps? A little help por favor?

Wutsup growers, im just shy of three weeks from germination and all 4 plants are growing fast under 540W MH. However, I never seen a plant do this and I also never really grew sativa dominant strains so i could just be tweakin. This is strawberry #17, she seems to be growing at a steady pace but is different shades of green, skinny and sort of droopy. She gets carbon filtered water from the fridge PH to 6.5-6.8, liquid seaweed and 16 hours of light. I run a de mh light that isnt air cooled but have controlled the temp fairly well but since its been warmer weather here in Chicago my temps have been in the high 80s as well as lowering humidity to 30%. Currenty getting a mini ac to cover 25 sq ft and a better humidifier. Any ideas what could be wrong with her if anything? All the rest look super healthy (chem cookies, bubba kush & rock candy). Thanks!!!!

I’ve had a seedling look like that before. I couldn’t tell it I over watered it, if it just had some root issues, or if it was just a bad pheno, but I just made sure I let it dry out more before the next watering and she slowly started growing normal leaves and turned out fine.

i was hopin so. thanks for da reply man

Yeah, that girl doesn't look happy.
80's and 30% RH is a very high VPD for veg. Either get the temps down or the humidity up.
Don't know if I'd continue with that girl.

This ^

Seedlings are very sensitive to root rot and damp off. Avoid over watering them at all costs. Id hit it with a little bit of hydroguard in the feed when it's dry again. It's going to be way behind the others if it recovers and it may not be worth the hassle in that case.

What sorta medium is that?
