The exhaust fan that's on it circulates the whole box, sucks air through the door.

Theres 6-3' bulbs, and 4-2' bulbs going.

Rockwool sounds about right, didn't presoak either but it didn't seem to be a problem with other generations.

Lol, you caught me, I have no idea what the pH is, I was told you don't need to balance the pH if youre growing with hydro, again it didn't seem to effect previous plants. But I'll keep that in mind.

I've got a Brom Thymol Blue indicator here, I'll give you a reading.
Jonesasaurus Reviewed by Jonesasaurus 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
