Hi guys I've woken up yo the plant showing this deficiency does anyone know what it may be? They are under a tsw2000 on 75% power at 30 inches above the canopy.... they are due the next feed on Sunday
I think raise the light a bit and maybe dim it to 50%, I am using the same light in a4x4, and still have it hanging at 38"or so on 75%.it's a very powerful light! Make sure rh is above 50/60%,I don't think it's nutrient issuse
