what is the browning spots and yellowing? im using 1/2 strength nutes every other water. superthrive 1 drop per. gal. organic soil mixture with live worms and castings. so its pretty organic.
Looks like you called it right off. Brown leaf spot, a fungus. I believe u treat it with copper. You can also just cut off the affected leaves if theres not alot. Been about 10 years since I experienced it, so I may be off a bit. Try googling it
i found out its black fly larva and black flies! they spread the fungus and larva eat your roots! diatomaceous earth kills them and stops spread with no plant harm. now i just need some DE! kill these fuckers and their fungi.
