where to start with all the things wrong lol, dude only used grow miracle grow no bloom, oh and fuck miracle grow. Dude wasted money on roots organic then feeding with shit. No phing, no topping. Noobs but at least I know what sunburn on plants look like now.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.
