I think Rick nailed that as for why and what I did is dial the the light down to 300 PPFD, for a week or 2 then I did a lite defol hoping the extra leaves would make it stretch more after the flip. It did not but this weekend it will be in the 20-22 days after the flip and I will trim it back to a near Schwazzing level and see what happens. I will post some before and after pictures and I will post more as it grows. 

At the end of the day, ask your self, does the plant look like you want it to? If not make it look like you want it too
