Ok, I have been vegging these plants for 2 months now. I have given them nute burn (or maybe the first time was just the AG browning i have heard so many people talk about) and definitely stunted their growth. I am using Fox Farms nutes (1/2 strength) according to their schedule (though i have stopped at week 4 and have kept that week going for 3 weeks as well as small amounts of epsom salt and superthrive with each weekly change. I also have an airstone in the res.
They finally started to really take off about 1 week ago (noticeable growth both up and outward) Most people i have spoken with said that even with the Pro 200 series AG that i have (with three lights) there wasnt enough lighting and that was slowing growth. So today i made a trip to home depot and bought two CLFs (one daylight and one more towards the blue spec), a fan to push the air out the window eventually, and a bunch of PVC piping to build a frame that i will be able to hang them from once they grow larger. Let's see how they fair now. They are def drinking much more water than they were last week.
I will also be wrapping the back of it in mylar and coming up w/ a better way to enclose the space with reflective material. I have been using a science fair board with mylar glued to one side of it as you can see in pic #3
looks like you got a handle on things and they look superb.
couple of things to point out.
1.) if those are all females, you are gonna have trouble with room. they are gonna shadow each other. you will see when they double their size that some absolutely perfect and HUGE fan leaves will be produced.
you may want to think about slimming down to 3 plants max in the AG.
2.) 7 females are gonna stress when they get bigger due to reservoir size limits. they will drink almost 1/4 of the res in 24 hours.
in fact what i saw when i had SIX plants going was that if i filled the AG up to the brim, in 12 hours it had gone down almost to the point where i filled it up from. that told me that the plants were drinking the majority of the water in the first 12 hours and less in the next. either they were stressed from low res level or that just may be what they due from light to dark not sure.
the fact is my 3 plants now drink almost the same. i fill to the brim of the AG without spilling over and in 24 hours it is below the "fill to here" indicator on the AG.
3.) not to be one to just point out issues, here is a possible solution.
check out the SOG setup explained around here. you may get some ideas.
i found the AG to be wonderful learning tool but it certainly needs to be more specifically used, IE: mothers or rooting clones. i am i the process now of setting up the second area to transfer my AG and mothers to veg out. gonna build my own dwc similar to AG but more betterer.
the only issue i am coming up with is that the AG produced so many good spots to clone from my THREE plants right now that i could have 20-30 clones. i only have room for maybe 2 or 3 on that 2 week rotation as explained by al.b.fuct
hmmm what to do.......
