Welcome to the farm!
Couple of things to consider.
How long have the plants been in the soil they are in? 3-4 weeks? (more like 5 or 6 weeks)
It looks like the plants are starting to show N or P deficiency. (good eye, I'll address that tomorrow I thought it was cal mag issue)
In the pics the plants are beginning to yellow mid way and down.
Since you are barely in flower my guess would be N but if that has already been addressed, then it is P.
I would go ahead and top the left front plant again, removing those top two branches.
Look how even the canopy would be on the plant itself and its sisters.
Trellis nets are to make an even canopy, right?
That would also answer the height problems you are going to have soon.
Better to lose it now before you get too attached to it.
Lastly, try dimming the lights some. They are brand new right? (yes brand new. I thought that in bloom they needed to be on 100%)
Could be 60% power is the sweet spot in your tent, especially with the height restrictions. (I'm going to mount the light to the bar tomorrow and gain about 8-10 in)
Seems like the leaves are wanting to stand up straight and tall but the light is beating them down.
The leaf steams are pointing up, but the leaf itself is pointing down.
Good luck and enjoy the ride!
