Definately not ready. You want them swollen and ripe. Banana's still green. You live in socal. You can let those go for a while. +props for adopting. More ppl should.
Way to wet. You want it to actually dry out just till it wilts a lil then water then. For me its every other day in my clear dixie cups of soilless mix /w no cloning solution. Sometimes i'll use dip and grow but I tend to forget.
I noticed your doing the mr green method. Good method but could be better. Your flowering beds would be much better off in 5"-6" individual pots filled with hydroton. Mobility to move plants around under the light is important. If you plant right into it the medium your going to have to see it...
you can fit as many plants as you can cram in there. I suggest buying 5" pots and filling it all with clones . fit as many as you can fit in the space.
Ideally indica's. Grab a pure indica or any indica dominate hybrid. Like Sensi Star, Hash plant, Pure power plant, C-99, Afghani, top44, aurora indica... and so on. Oh these all have the shortest flowering times too.
I prune if my plants are going to be over 2ft tall. I cut about 4-6 inches from the bottom all the way up leaving only the fan leaves. aka lollipopping
