If your going to put them outside then you should wait until they show pre-flowers on their own. Otherwise you will waste a month or so re-vegging it which will hurt size and yield come harvest season. They should show pre-flowers in about the 6th or so week indoors. I would already be adjusting the light to coincide with the daylight hours outside. I don't even know why they aren't outside now. you're wasting elec. in my opinion sunlight is free ;)
 
the reason they aren't outside yet is because we could still get a frost where i live
