Everything looks great man! Cant wait for final weights, etc.
I think you are going the right thing by cutting back the additives.
I just was talking to my buddy yesterday (I only see him every few months) and he was complaining about how much he spends on nutes. He's been growing for about 8 years now and I think as he went on he kept adding more and more thinking it was better.
His final product is not impressive, they finish quick but there's almost no second swell.
I can't bring myself to tell him his shit is fucked.
I don't go through them very fast, I try to keep it super light pretty much the entire grow. I will boost about mid flower and then taper back off. I don't use many nutes during Veg, pretty much just what I put in the soil.
