Coco is my medium and I didn't use that much guano. way under its rec dosage. I sprinkled a tbsp across the top of the soil. I had been giving it 35 ML of PBP / gallon and the recommended dosage of LK (cant recall offhand)

The water is R/O and I am unable to check the PH, I will pick up something today for it.

I am growing it in my PC and the temps have been fairly stable at 78-82

The top of the main bud has turned brown.. Although it doesnt seem to have gotten a lot worse. just the leaves that were affected are browning and dieing off.

My hands are tied right now if fixing her requires a bought product..
