Have some problem with bud leafs. It's looks like potassium def or maybe nut overdosing. My PPM meter was not accurate and I switched to another one. The old one showed 100 PPM less. Thats why I gave 800 PPM instead of 700 PPM
wow that plant is looking good. Very well structured. I guess I have to learn a lot till I reach that level.
But I guess it also has something to do with the longer veg. My Autos went into flower after 3 Weeks of veg. Hard to get such a structure in that time (at least for me)
Anyway, good luck with the grow!
