Get a Sulfur pot; Best method. :slight_smile:

just to clarify, would that be for the purple stem or the powdery mildew??


I butchered this thread, I’m fixing it, sorry, lol…

purple stem – maybe phosphorous deficiency, but most nutrient systems formulated with cannabis in mind have plenty and so it is more often a magnesium deficiency and a cal/mag or epsom salt(magnesium sulfate) often is the remedy.

Sulfur pot for powdery mildew.


The Epson Salt would be for the purple stem
