Hey guys I'm in week 4 of flower with my white widow from ministry of cannabis and im starting to get some brown, black spots appear on a lot of the fan/water leaves. I haven't been able to match it up with a particular deficiency, mold or bug so I'm struggling to pinpoint what it is. Other than that her buds are thriving and covered in trichomes and just smelling dank as anything! So yeh any help would be greatly appreciated if you need more info just ask.
I'm terrible at pegging Deficiencies but I do know that 9 times out of 10 the cure is just to flush the plants, include a little Cal Mag in the water and make damn sure the water is at 6.5 PH when you use it.
