hey there Lastestagecapitalist, so there's a few things happening here. All this began when you overfed like two weeks ago, then flushed. you went from too much to not enough nutrients basically, and there's a fair bit of "inertia" on a plant. so when it got over fed it takes quite a few days to fully recover and in the mean time the damage spreads although in a limited way. Does any of this make sense? so when you flushed you took out a lot of nutrients, but the plant is still in flower mode and now you're getting phosphorous deficiency based on the yellowing you're seeing. Just work your way up to the right level of nutrients slowly, these kinds of big fluctuations are not a good thing for the plant. You're actually doing well ! Hope this helps ! 🚀
