I have 3 Alaskan thunder fuck plants. Purchased feminized seeds - not auto flower. They have been in veg for 5 weeks. 18/6 light cycle. I'm noticing small white hairs. Looks like it's flowering? Should I be concerned? Was hoping to veg a couple weeks longer as I have numerous other plants, different strain that is not showing these signs. Wanted to flower them all at the same time. Any info or advice would be great.
