Salts building in your planter, causes lockout. Ph out of whack also causes lockout. Check both.

The brown spot problem is still the same. I reduced the fertilizers to 1/2 dose according to the week after 1 week of just bottled water. The pH of the solution is generally 6.3-6.5. Apparently, the central cola is thicker, but I find it hard to notice the difference.

could this be due to the PH being too low?
I watered 3 days ago with PH 6.3 Ruoff was 6.0 today watered with PH 6.6 runoff was 6.1 Can the brown spots come from the wrong PH ? fertilizer is full BIO BIZZ CHEEMA, worm humus and mycoriza

I am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.

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.

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳
