SCROG advice

Hello fellow growers. I have a question on my current grow and flipping to flower. My tent is a 4x4 and it's my first first time growing indoor and scrogging.so I'm sure I've done some things wrong. Anyway, am I going to have an issue with the back two plants playing catch up? They're about an inch away from reaching the net and I'm worried I'll run out of space because of the larger plant. Should I flip sooner rather than later. I'm thinking they'll be ready in a week maybe two? But by then I'm worried the front one will have taken up most of the net.

For the life of me I can't figure out why they are growing so slowly compared to the front one. They've all been started around the same time one just being 2 days behind. It's been that way from the start. All different strains, but all are indica. (for some reason I thought one of the back ones was a sativa for a while. Must have been too high and looking at one of the crosses instead.lol) 46 days from seed. A bit long I think, I had some early transfer issues but they recovered.

Raise the shorter plants up to match the tallest...if they catch up later you can always remove them.
Don't forget to account for stretch.
Best of luck and happy growin'

Thanks, I did exactly that. So much easier to train with the netting too. Found lots of nodes hodingt in there.
