Yea I'm in PA as well with my first guerilla grow and mine have just recently started flowering. Just be patient they will flower eventually but considering these are a little late you may encounter the same problems with frost as I might have. Frost comes around mid-October and this leaves us with a good month and a half to flower. Hopefully this is long enough to finish but you may have to cut early or fashion a mini greenhouse to extend the season to fully develope the buds. If anyone here knows if its possible for a plant to survive frost with minimal damage it would be helpful to us both
