My 3 DWC mother plants

i just started 3 female clones Grape ape, grandaddy purple, and purple piss. In 3.5 gallon buckets painted black with 2 gallons of water in each bucket. and there is two air pumps a dual outlet and a single outlet. I was wondering.. is it ok if i use water thats 80 ppm?
I'm using GH 3 part nutes. I currently have the nutes as 70 micro ppm, 100ppm grow, 30 bloom with 80 ppm water, 280ppm in the grandaddy purple and the grape ape.
I started using 20ppm water but then i got my license suspended and i cant get the water from the machine. is it alright to use 80 ppm water? I'm going to use these as mother plants
The purple piss is 480 ppm
what should my ppms be? and how much of each the 3 part should i use? and how much water should i be using? Ive tried this one time before i had my card but i jus left it because i was never home and it died.

Heres the Grape Ape

Heres the Purp piss

Heres the Grandaddy purple.. got a lil stunted.

Dude using gh 3 part its all on the label. I think ur concern is in the wrong avenue. If ur veggin thatn after all 3 nutes are mixed I keep it as follows.
clones i dont use nutes maybe a root builder and distilled h20
transplant after 2 weeks and i mix the 3 part to 150 ppm
after that i start blowing them up week 3 400 week 4 600 week 5 700 change to bloom formula and start back at 600 i continue up to 900 at the most 1200 depending on what ur plants can take. depending on the strain and how good u keep ur other requirements i.e lights water temp air and humidity u can run em up to 1400 ppm without any problem....its all up to you.

alright thanks dude.. my bad if its in the wrong section
