@VermontGrobo one big factor to considered also is how many ML you are applying per minute… Based on Pump size / how many plants / if your using bubblier flow reducer etc
I personally found more short cycles of water seems to work better for me than longer cycles… (I’m not saying your chart is wrong just saying my thoughts)
Right now I just started flower feeding 1.0 right now… Plants seem to love it…
An observation is since I have been foliar spraying them less nutes is needed in my feed… My magic number this grow for Ec has been 1.2… I know it sounds low but the plants seem happiest at this feed…
One more point to add is when you water more often you are always supplying fresh nutes to your plants so in my opinion high Ec isn’t needed then
