how far from the plant tips are the lights

all dees Qs are trying to establish if it is a over heating problem

 

are you positive it is not an insect infestation????

insect infestation is the most common cause

a maginifing glass is a must

check underneath the leaves

and the top and bottom of the pots

 

theres a chance it could be a disease

you must steralize the grow room and everyting inside including all your hydro equipment after each crop, just before your next grow, is best.

do you follow practices like dat???

 

it sounds like they are responding well to the flush

which means its probly a nutrient prob

yes even a mild heat stress will slow plant growth

to maintain low and stable grow room temps is a must

root zone and grow tips are crucial places to watch colsely, use temp gages
