Weedhound is right 6.5 is waaaaaaaaaaaay to high for hydro I'm in soiless and i stay under 6.3 at a minimum, and i like to keep it around 6.1 . I think lowering it is gonna help TONS! GL!
Cpt. Zissou Reviewed by Cpt. Zissou on . leaf discoloration? I'm growing 6 plants under a 450watt MH in an ebb n flow hydro system. They're doing great- three weeks old, but I noticed one plant had a slight yellow discoloration on two leaves. The one on the left, and the one of the right. The one on the left is the largest and probably easier to spot in the pictures. What does this mean?? Thanks! :rasta: Rating: 5
