you turning your whole backyard into a grow? They sell fabric raised garden beds on ebay. id just get a bunch of those fill them up with humus/tirplemix/comost mix and then build a greenhouse over them
wait till you need to start watering nearly every day. They can prolly get to about 18" in those 2 gallon pots. use good soil when transplating put in 5 gallon then a 20-50 gallon
re-read the orignal post "After a 3 day flush she showed signs of deficiencies, I sarted feeding her, at first with a nute that had no N." this is huge mistake.
