Hi everyone. I've discovered rust spots on my leaves. I can't tell if it's fungal or nute burn, the rust doesn't seem to be coming off on my fingers which I think is a good sign? Does anyone have an idea of what it could be and whats the best 'next step' to take? Thanks IA ✌️

It’s the cal-mag flushing out. Nothing to do at this point in the grow. Ladies are looking good and happy growing!!!
