Mainlining/Manifold Training: How am I doing? (Gorilla Glue and Runts)

Hi these 4 plants have been vegging for 1 month and I've already got (more or less about) 8 tops on each according to the guides on how to do mainline or manifold training. Any feedback on that and how I'm doing with it? (P.S. I know there was some nitrogen overdose initially).

Never seen better.
