New to growing , issues that I think need addressed

Its a little high, but not too bad, I run 6.0.

I’ll drop it back to 6.2 but they are doing their thang lol .

My monster crop / super crop / lst ladies are thriving very nice . In reality they are about a ft tall . Bent and tied down they are about 8 in from the soil . I’m going to let them get about 1ft taller then I hope to flip them . But I got to say the mars hydro tsw2000 wasn’t the greatest choice of light .
