General Hydroponics Flora series feed chart WTF?

The Simple (not expert) recirculating chart suggests that for early veg i should be using 10ml Grow, 7.5ml Micro and 2.5ml Bloom per gallon of water. well i got 4 bubble buckets, each with about 4 gallons of water in each. i have a 20 gallon res i use to mix etc. I figured i would go with 2/3 strength called for by GH Feeding chart. So first things first. the micro. 7.5 / 1.5 = 5ml per gallon. 5 x 4 (4 gallons per bucket) = 20ml x 4 buckets = 80ml of Micro.... Then 105.6ml of Grow and finally 27ml of Bloom


This seems excessive to me... anyone have some input? my tap water comes out at 320ppm and i don't want to burn the shit out of my plants.

Thanks guys, i finished adding all the nutes to my res. PH 5.82 @ 910ppm

I hope this doesn't nuke my plants. one strain is showing some sort of deficiency (or nute burn?) so i hope this cures it.

just figured everything out, i bought 1000ppm Calibration solution and put my ppm meter in there. registered 1320ppm. so i thought since my tap water comes out at 320-330 that would mean my tap water ppm would be 0-10. but after calibrating it comes up at 220-240. so essentially my problem was a deficiency and my plants are loving the 900ppm (turned out to be 700ppm) poor babies got starved.

Makes me wonder if I should get some calibration solution for my ppm meter. It reads zero on rodi though like it should, but it still makes me curious.
