cuz honestly the more I look at it kinda looks like pest check for gnats flting around buy yourself one of them yellow sticky pads and hang it in tent/room and really check your medium just in case if you are pest free id say its a potassium def
What problems do the gnats pose? I have a few. One fly strip up, gets most of them. Going to put more fly paper up tomorrow. Can pH issue cause lockout of potassium? Sorry to butt in, just think I have similar problems.
