are you feeding full strength? what do the roots look like? are you misting? if so, stop.

lets see the roots.

ph? tds?

you feed once a week! that seems way too little!

it's hydro. he changes the res once a week, which is fine. the plants are exposed to nutrients the whole time.

pump is on 24hours? or does it cycle off for cooling? what is your res temp?
