Yes! I've read that this can be linked to low humidity which sounds about right. Thank you

When did you get this issue?

On my previous grows wasnt anything major. All of them finnished just fine and carried beautiful buds.
Didnt seem to spread either neither could I get the cause.
Would be good to the know the cause tho.
I have one now with the same symptoms, but I topped it, might have pinched the new growth abit.
All in all, keep a close eye on it, when it starts to worsen or spread, keep searching the net and do let me know.
If its not spreading or becoming worse, Id say youre fine.

almost any plant can catch rust, if you've ever seen a lawn with round orangish brown circles this is likely rust fungus, A clean growing environment and clean clothing when you enter the grow room can help prevent it, a filter on your intake may help as well.. but the best measure of defense is treating with an organic fungicide before you have a problem.
