Need help, pale curling leaves with brown spots

[Patty smith]

One of my chemdawg plants has not been growing as good as the others it is pale, brown, curling leafs, some are starting to turn purple around the edges, and today I noticed a couple dead branches with no leafs and almost looked dried out so I cut them off. I've tried calcium, magnesium, and iron. so far nothing has done much so any help would be appreciated!

Hi Patty
Try putting 'cannabis leaves leaf spot fungal infection' into a google image search. Do you think it could be that? Or similar fungal infection? (rust spot). It's hard to tell.
If it is you will need to remove all the infected material immediately.

Thanks for the feedback saturnalia, I am planning on just cutting it down I'd rather be safe than sorry since its so close to my plants

Hi Patty. That sounds like the best strategy. Better to lose a bit than the lot. Did you search like Sat said? Was it like what you had?
