Not mold

Are your plants getting dripped on by birds or trees above them

Kinda looks like powdery mildew. I had the same thing. I sprayed for mildew and havent seen it since. But i really dont know if it was mildew or something else, like maybe a bird, or a type of bug that throws up white crap. Shoot me an @Alienwidow if you find an answer. Thanks.

Did your plants go from gloomy weather to intense sun ,with dew or possibly rain water on the the leaves??? This is sun burn on hibiscus. Looking familiar? I think this may be your culprit.

Looks like a pH issue judging by the lower leaf miscoloration and necrotic spots

Well dude is using city water and miracle grow. So his shits fucked up. I just haven't seen this kind of spot. Was thinking it might have been sun burn. I'm sure his ph is off.

It's my opinion only but, I know that Cannabis leaves are much more succulent and tender than Hibiscus and you see how tore up that Hibiscus leaf is. That leaf is very thick and much more rugged and durable compared to the Cannabis. Im pretty certain sun burn has alot to do with it but Im also pretty certain that there are other things at work here too.

Indeed but the white spots were just odd to me, thanks for the input.
