315w cmh GG#4 3x3 tent grow

When I transplanted them I watered with half strength rhizo at 6.5ph using purified water, I havnt grown in over 2 years kinda forgot how coco is with cal mag especially using ro water, within a day the were not looking good, leaves were bear clawing and turning colors and some leaves starting to deform, I panicked and bought some cali magic and flushed them with ro water and normal strength calimagic and 2 days later starting showing signs of strong normal growth, it has been about 4 days now since and they seem to be snapping back, wish I had pictures of before they did not look good, also my setup is a mars hydro 3x3 tent with vivosun 315w cmh with Phillip's 315w green power 3100k bulb, a vivosun 6 inch variable speed controlled 390 cfm inline fan hooked up to a willhi temp controller and a vivosun 6 inch clip fan for circulation, I also have a willhi humidity controller that gets used on lights out, I switch inline fan from temp controller to humidity controller, as humidity gets up to 70+ at lights off without inline fan controller setup, I am also using 7 gal smart pots and using only canna coco, and for ph and ppm I have the growers tool box from blue lab with ph and ppm pens, the clones are gg#4 from dark heart nursery, I have 2 tents running at the moment, third tent will be up as soon as I can find another strain from dark heart that I like that's in stock around me, hoping for gmo cookies, wedding cake, purple punch or vanilla frosting
