I have a couple of plants in my tent that have yellow powder on them. Mostly on the stem of the leaf. It’s NOT white like powder mildew. And my plants are NOT in flower so it’s not pollen. Anyone have any ideas? PLEASE HELP !

I’ve never seen this before, I’m set to watching to learn the diagnosis, if any.

It’s maybe rust @garrigan62 @Bigboy_c
So a fungi treatement may be the solution, like powder sulfur or with a sulfur burner or copper spray
