Any suggestions on what you think the problem could be with #2 could be welcomed. Air pots, soil dries out 2-3 days, temps stay in same range, since sick no training was done, brown spots starting at old growth and moves up plant on big fan leaves 1st then rusty look as progress?

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Would putting off my first feeding for a day or two do this much damage to the plant? I've given it 2 feedings since then and hoping it's on the right track as the new growth is nice and green.

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?
