Ok i moved the 3 plants on the 400 HPS side to the left side with the 125 floro, and there is an unmistakeable improvement. they have popped up and are liking that light better.
Here are the roots for the front 3 very healthy roots i think.
My rez is NOT light proofed very well, im thinking about gettting a different rez. one that will be easier to LP.
These containers have a drawer and some light leeks inbetween the pots also.
My nute regime is GH but I only put 5ml of micro grow and bloom in there, as they are still young and I dont wanna make them toxic. Check that, i put an additional 15 ml of micro in the right rez , cuz i thought they might be wanting more N. But since i put them in the left rez they have improved
