Nutes, Calmag

Ok i need a lil help from some fox farm peeps. i just bought some grow big, big bloom, and tiger bloom. I have never used these nutes before and i was wondering if someone would give me a good feeding routine for my babies using these three nutes. also how much cal-mag should i be using to adjust RO water?? Thanks guys!!!

Right now I am using CalMag at 2 to 3 cc per gallon and that is with tap water. I will probably keep bumping it up untill I get to about 5 cc PG. Plants are only 3 weeks right now. Don't know if this helps you.
