According to the Swazhing method you do a heavy defol the day of the flip and again 22 days after. I have done that twice with no problems as far as hermi's are concerned but I was not thrilled with the results so I am doing less defol this grow.

That said, I wouldnt do a heavy defol once its 22 days past the flip, and it looks like your are, but tucking and pulling a few now and then that are blocking light doesnt seem to hurt anything.
