After thinking a few minutes. I think you entering the strech phase.

So fasten your seatbelt's this is going to be a bumppy ride

I would continue to LST With string and weights to take full advantage of the horizontal space. You will more than likely have to prune and top during this phase just to keep things under control even though it is not recommended in the flowering phase.

I think if you make it thru the next 3 weeks you are in the clear growth wise.
