Everything goes haywire….it’s probably a lockout, also. It usually looks like a calmg problem at first, then as it progresses she’ll begin to fade, and so on. It’s like she’s not able to uptake anything. It’s fine in late flower, but it’s going to keep causing issues for you I’m afraid. I would put a minimum of 4x the pot volume of water through her in hopes that’s enough to flush the medium fairly clean.
