I’m on my second week 3rd grow. cool if you help me out so many mixed things online. I am using really good 5 stage R.O system. Auto flowers. GG and BB. FF strawberry fields and promix 20 percent perlite. How much cal mag per gallon? Is there a way I can add it to all waterings including feedings. This way I can buffer the ro water? I haven’t used any calmag yet. Using fox farm trio 1/4 to half. And can I really use big bloom every feeding and that much of it 6tsp. 1.5 to 3 tsp a gallon? Thank you In Advance

I do 5 ml. I switch between CalMag and Epsom Salts.

I haven’t used that nute line. Maybe @Newt could offer some advice on it?

You will want to bring your RO waters tds up too about 350ppm. Water with too low a tds will not hold its ph so this is crucial during water only days. I use calmag at 5 ml per gallon and I also toss in 1/4 tsp epsom on water only days.

You will need too using RO

Shouldnt give any nutes until runoff tds reads bellow 1000ppm.

The 6 tsp stops being a thing after a few weeks in. It will drop to 3.

You will fall into a schedule with FF as your plant grows. It will become water, feed, water, feed.

I do 5ml
