Rust spots and yellowing deficiency

[Thechickenwing]

I fed 3 days ago with nectar for the gods 1/2 strength to my plants which are 2 weeks into flower. I’ve never had any issue with bugs or ph levels which i maintain quite well. Idk if my feed was just too light or if maybe I should flush them out because of lockout
