So to review:
1. I generally top between weeks 3 and 4 in veg, depending on how long I plan to go (in veg). I like to leave 1 week for the plants to recover from a topping before initiating flowering.
2. One solid lolipopping is generally all thats needed. I like to do it the same time I defoliate for the first time, Remove almost everything on the bottom 1/3 of the plant. The only time I'll leave something is when a low branch is well developed and has some decent height to it already. Everything else goes............
3. You guys know how I feel about defoliating......it's made a big difference in my grows. But it's even more important under LED's, due to their great light spread. I generally complete the first deep one the day I switch to flowering, then I'll remove more leaves that are blocking a bud site below them. These days, 3 weeks after my first defoliation, I continue to remove about 1-2 handfulls of leaves daily. Always consider removing the largest of the sun leaves, and don't remove small leaves (for now).
Today is day 21 in flowering, at least 7 more weeks to go. The above defoliation pic's were from the Orange Gasm grow over on THC Farmer.......
