I would top the main down to a couple nodes then top the branches at a couple nodes up and let it bush out a bit. It’s way harder to shape clones than seedlings.
To me looks like week 3-4 of flower at latest. It be better to see the full plant. In flower it’s gonna want less nitrogen and more potassium and phosphorus. They are putting on right now so I would be pushing them bloom ferts right now. (What are you using for bloom fertilizer?) (for that matter what have you been using for fertilizer so far
I've been all over the place. I was watering correctly, but my fertilizer was all wrong. I had a lot of yellowing leaves, but it wasn't due to watering. I couldn't get my pH level right no matter what I tried. Nitrogen was definitely my issue. However, since I saw the first bud I spent hours reading/watching (I didn't want to lose the plants and there is so much conflicting info out there) and I finally wound up using a Reefertilizer BLOOM 5-30-20 with every watering and I think I've just finally turned the corner on combatting the yellow leaves and correcting the pH levels. I will upload pictures tomorrow of the worst yellowing (hopefully I didn't delete them) and where I'm at currently. Thank you for replying. :)
