How do I make the transition from veg to flowering stage?
Change lights schedule. If you did have on 12/6 or 24, start on 12/12. If they are inside make sure that your plant room is in total darkness ( pitch black).
People have different methods of starting to flowering. The Roberts bible i downloaded would be best. It’s on the main page. I slowly turn my lights to 12/12 over a few days. Some people turn it dark for 24 hours then to 12/12. And yes you want it pitch black. I sit in my room to see if there is any light coming in.
