I just found a spot that is making me think bud rot. I so hope it's not true. Slight discoloration of pistols and leaves in a bud node. I added a picture in this weeks section. Please tell me it isnt bud rot.

Please check the last pictures I have posted. This is about a week after transplant, and the plant also has burnt tips. Are the brown spots from something other than transplanting into hot soil? They are in KIS water only soil and I have only been giving well water, ph is 6.8ish

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

Brown, curling leaves?
I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

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?
