Yellow curling new leaves, need help please

Sociophobe · Jul 28, 2016

My plants is one month old and are very bushy and nodes are close to each other.
I grow in coco with advanced nutrients.
Ph is always 5.8 and ppm is around 800.
Week ago new growth start getting yellow and and new leaves are curling.
Pictures are down and closeups if somebody can spot the problem and point me in right direction...

Did your room get too hot, possible over watering? Did you top those?

How far away are your lights, and what kind of lights.
What are your night time temps.

I agree and possibly to much water

Wow looks like its just melting...even lower new growth is having issue so prolly not from light being to close to the tops...what about overall temps in area? Plenty of perlite so most likely you have good drainage but are you letting runoff water sit in the bag that the pots in?

Could be...Nutrition deficit, ph, and I would say heat.
