greenAFanswered grow question 2 years ago what i do is take the FF sched is appropriate to your grow. Then adjust I am running autos so the sched EC is way to high, even high for reg fem, and then adjust accordingly. So say im in week 3 and the EC range 2.5-2.7 but I want to feed at like 1.2 I used 40% of what sched calls for, then u can make minor adjustments with the nutes you want to hit your target EC. There's 1000 ways to skin a cat, that's the way I do it.
