LST is looking good Archie. This opens up the middle a lot and forces the 'inside' branches to grow. If you do it right....in a few weeks you shouldn't be able to tell which leaders are the mains! Yes, timing sounds right at about 3 more weeks. Don't rush things now...they have a lot of growing to do before flip. When LSTing as you are , don't get too aggressive with them....after you tie them down like that ...you need to give them time to react properly and start to grow.
Suggestion...get on your belly../back on the floor and have a close look at the under growth and crappy stuff growing down under the canopy. Trim all that little crap off...all the little piddly branches and three bladed leaves ok.When your done doing that...looking down from the top...u shouldn't be able to tell , that u just trimmed all that crap off, understand?
Everything is looking on point and proper...cheers eh!
