Nutes ppm and humic/fluvic acid?

Hey guys so I'm not sure about this, but do I need to use less nutes if I'm using Mr Fluvic in hydroponics? Right now I'm at about 550 ppm and I'm going to flip tonight to 12/12 light cycle. I heard bc the nutes become so "available" that I need to use alot less than what to manufacturer says? Using general hydroponics nutes..thanks in advance!

it should but use your ppm/EC meter for sure.

OK I will but do you think 550 is enough? I raised it to 750ppm bc I'm thinking it's more like 1500ppm bc the nutes are so "available". Thoughts?

write down your ppm drop per day without fulvic and then do the same with fulvic.

let your plants tell you how much more or less they need.

i would think 750 should be plenty. you can always keep going up slightly and once you see tip burn, back off to whatever didn't give you burn.
