How do these look? .... any suggestions?

What’s up guys this is my second grow and I am in my second week of flower and wanted to get some opinions on how these girls look and what I can do to improve... they are two master kush and one skywalker og in the back...it’s a 3x3x6 tent with 400mh in for the first two weeks of flower then I’m putting in my hps . I did some LST and some super cropping to get an even canopy( even as I could) .. I’m coming up on my 3rd week of flower so should I clean up the bottoms and middle by cutting some fan leaves and “sucker branches” to direct energy to open up more bud sites? Feeding general hydro 3 part at bout 500 ppm.. any and all help would be appreciated sorry if I sound like a dumbass but like I said this only my second grow
