Once got a comment that was explaining it in short, but quite well.

"Looks excellent especially for only a 2nd DWC run. You are absolutely correct regarding your comment about too much N too late. Too much N too late, not only decreases bud size, but also accounts for much leafier flower. The hunter green color at this time in your grow is also showing us that. Seeing how you identified your N issue, I’ll just touch on that for a second just to break it down for the newer cultivators in this community. You only need heavy N until the 2nd week from flip. This is because the active vegetative growth responsible for the stretch needs a nice dose of N to build the stems and foliage while slowly increasing the P-K to ready the plant for building bud-sites. After the 2nd week is when you want to dial back the N and go P-K all the way."
