Yes, as the day's continue to increase in length, they will revert back to vege, tho they will continue to flower for a while now, and the switch back will be a bit more stressful and take longer if left on the natural light cycle. If possible you can use supplemental light to artificially increase the light cycle and trigger re-vege sooner.

Good luck and your girls are lookin awful nice! They will be TREE's if you vege em until August!!!
