roots organic question

I have been using the roots fert line. I am running into def. problems. I water with 25gals and when I pre mix my 25gals. per the instruction I get a ppm of about 800. Now I know I can get my ppm upwards of a 1000. But with the roots because this is my first start to finish grow can I bump up my feedings to around 1-1200 ppm? The plants are under 8bulb t5hos until flower....Should I do the math and bump it up to 1kppm? or more? Yhe plants are severly over vegged do to my local power company taking there sweet ass time installing my 200amp transformer. most are 4 plus foot.

it depends on many factors if u can go at those lvls , u better try to increase the ppm slowly like +50 or +100 , when u plants take a dark deep green color that means u got no more room to increase the amount of it , some strains can handle more ferts than others

that math will be fun!
