hey hi steadyeddie,
I see you have already lowered the screen as compared to where you had it at first - good move!
Yes your plant looks like she is growing very tightly, which makes it hard to train any branches into the screen, so your departure point isn't easy to begin with
Also I saw how you have contradictory information about how much your plant's strain will stretch.
- If she stretches alot, the way you have the screen set up is just fine and she will grow into it in the next 2 weeks or so. (in case she doesn't after all, you may not fill your screen and thus not benefit fully from the scrog technique this round)
- If she doesn't, it may be a good idea to lower the screen a bit more to force her to spread more now. (If she then decides to stretch after all, you may fill your screen too fast and get a cramped situation - meaning you will have to pay more attention to air circulation & humidity and making sure you don't get budrot)
So, not an easy decision! But, perhaps as consolation: I read somewhere that scrogging just takes a bit of experience, and you're not a real pro at it before you've had both a screen that didn't fill and an overfull screen. Also, remember that you WILL have a yield either way, so it's not a life or death kind of thing here
In any case you can remove some more of the undergrowth to encourage her to focus on growing her top branches out. You can start by removing a few strategical fan leaves (those that have the most effect by being removed).
By the end of stretch there shouldn't be any growth left below the screen, but since your whole plant is still there at the mo, you will want to go progressively as she develops her tops
Hope that helps a bit!
