6 plants SCROG 4x4, 6 different strains

Hey all. Im doing my first scrog.
I have 4x4x7 tent, 600w hps with extra t-8/cfl.
5/6 gallon fabric grow bags. I use advanced nutrients PHP connoisseur for flowering and bud candy. Pro Mix/perlite/vermiculite/fish compost.
I used 2" hexagonal chicken wire and bamboo poles to make the screen, its also 4x4.
I have 6 plants under there. 1 Blue Medi-Kush, 1 Pineapple Chunk, 1 Gigabud, 1 White Lavender, 1 Tangilope, and 1 Sugar Black Rose.
They are all within a wee/week and a half flowering time of each other. Some are responding better to scrog then others but they seem to be doing ok.
I'm about 10 days since the 12/12 flip. I have the screen about 9 or 10 inches from the pot.
Starting stripping the undergrowth a few days ago.
Im not sure if i let them grow into the screen enough, its my first try, but they look like theyll make a full screen 8 weeks from now
DID I DO THIS RIGHT??
Any guess on a yield.
Is there an easier way to water the back 2 plants, i currently crawl under there and do it a cup at a time.

Those pics are from a couple days ago, they have actually filled in a bit more than that now

Things are looking good, but you made your life a little difficult with all of the differing strains and without having access to the back. As they continue to fill in, you want them all to finish about 4 - 6 inches above the screen, so your tucking will wind down between 14 and 24 days. With all of the plants you have in there, it might actually be a good thing that you didn't veg them to the point of training under the screen before flowering, but you should veg them out a little to take advantage of your screen next time. You could probably do the same thing with 3 or 4 plants. You are probably stuck crawling under there for now unless you run some type of irrigation lines or something. I made carts on wheels that I mounted my screens to, so I can wheel them in and out. It has been a lifesaver.

just build yourself a long wand out of PVC and a funel then you can just guide that to the plants from outside the tent and dump your water into the funel
