I would start with LST before anything else. While in veg it’s okay to have lots of growth as long as you’re keeping air moving. What’s your end goal with your grow?
So with your lights you might have got a par map it would show your light intensity at certain distances from your light. For these plants we want to be a certain distance from the canopy to hit a par range some people use ppfd's(micromoles) to determine their light intensity. All lights are different so never follow a "rule of thumb". Hope this helps.
Looks good! Any idea how much PAR the plants are receiving?
And Ph Perfect nutes meaning Advanced Nutrients?

Looks good, may be time for some training, clip a few of those sun leaves to expose bottom growth. Your well on your way.
