well let's see, you do or don't have an exhaust fan that works? how do you get consistant fresh air?

by planting cubes do you mean rockwool? did you pre-soak the hydroton and rockwool?

you say you don't know the pH and you can't check it, but you know it's a stable 6.5? which is it?

by the way, you want your pH for hydro to be between 5.3-5.8.

how many bubls do you have? that's a big space for fluros.

headshake Reviewed by headshake on . Yellow and brown spotted leaves Alright stoners and stonerettes, here's the problem. Theres these plants in a small cabinet grow box, Purple Haze x White Widow clones, and they have began to develop yellow/pale leaves and brown spots, some leaves are becoming crunchy, and dead. An opinion of one of my colleagues suggest that this may be the result of the cabinet being too hot, due to a recent heat wave. Can anyone help me diagnose and fix my delicious babies? Rating: 5
