what could this be??

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.

I have the same thing going on, but just on the fans. About 2 weeks to go, could it be the leaves dying off?

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 fear its a fungi but it could just be leaves falling off right? that same plant was nearly naked of leaves when it started budding... ???

thanks supchaka

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.
