Growing these clones since August 3rd, I have them in a 2x4 tent and I am a first time grower. Plan to flip to flower Oct 3rd. Suggstions?

I seen that limb as well, in mine I won't too that I'd lean it over a couple squares. Whenever I've topped at that stage I didn't get a big fat cola on that limb, just the individuals below it. I seen a guy that when flipped to flower he'd put a syrofoam cup over the tall tops for a day every three days to let the others catch up. Don't know if it works I've never tried it, have you seen that before?

@Mr. Grow It during veg I was using a few different things (liquid kelp, liquid karma, vitamino, and a banana water my girlfriend makes for me). I did have some yellowing after about the first month, the only thing I Wasnt using that I saw everyone else (YouTube) using was cal mag, a friend told me I didn’t need it so I still haven’t used it to this day. He actually recommended epsom salt (it’s been working so far). I did see your videos on YouTube and for flower I purchased Early Bloomer and Liquid Blue from Blue Planet Nutrients.
