Well I lst'd for the first time on my last grow and I think I did it about 3 weeks into flower because it took the first two weeks for them to even show sex. I'll do it the same way this time because I don't want to do all that work on the males so in my opinion no it's not too late at all. Just be gentle in pulling the branches over and don't snap them. I remember reading somewhere (can't remember where) on this forum about people using bolts to hold the branches down; tying bolts to the branches and sort of letting them hang and pull the branch down gently. You might run a search to see what you can come up with. I ended up using that green garden tape that you stake trees with and it did fine and had a nice stretchiness that I liked to work with.

Great work on the clones! I tried cloning a few when I first started and mine just rolled over and died right off the bat.

One of my big loves about hydro is removing the possibility of watering incorrectly too.....I always was terrible about that in soil. Just THINKING about "watering" makes me tense, lol. Too much? Too little? I always hated that!
