I don't spray my plants but I was thinking it might be from holding it up near my led light when in swapping to a bucket to check my pH levels ect, could that have burnt it like that ?
No signs of any pests that I could cross reference
I thought leaf septoria was black spots kinda like mold. Maybe different kind of leaf septoria?
I think black is just more advanced. I've only personally experienced it with tomatoes outside. Started out looking like bleach spots, then turned brown, then black specks and dead leaf. Plants still grew fine and produced plenty of tomatoes but they were a bit smaller than unaffected plants.
Well i see you on alot of post, you know what your talking about. So what can he use for treatment?
