I was just curious how many ppm of cal mag you guys would recommend using to supplement 0 ppm RO water that I am going to be using FloraNova bloom with?

The recommendation on the bottle of 10ml per gallon for accelerated formula yielded me like 500 ppm which seems WAY too high. Ive cut it back to around 140ppm which "felt" better to me but I just wondered what you guys thought.

This is a soil grow, with a 4x4 grow area with 2 HPS 1k watters and 1500ppm Co2.

I only use 5ml for the same reason as you; the ppms just shot up there. I don't have cal-mag issues. The 10ml may be a recommendation to resolve a deficiency but I've had good results with 5. Hope this helps.

Thanks for the reply! Do you happen to know what ppm 5ml leaves you at ppm-wise?

Been a while since I checked, but with RO at 15 ppm 5 ml gets me to about 150ppm.
