@sixstring2112 if i cut the cal nitrate in half it would be a ratio of

(and prob half that for the younguns)
jacks has a shitton of mag sulfate in it. and the cal nitrate has a ton of calcium. to the point of where i dont see needing epsom maybe my spreadsheet is wrong tho
FWIW for the macros mel frank recommends 300 N/ 80 P/ 250K/60 Mg
jorge recommends 250 N/ 80 P/ 300K/75 Mg/200Ca
the GH i used to use had a SHITLOAD of micro. i think it was 1.5 G/6 B/ 22.5 ml micro per gallon at full strength (plus 1/2 tsp of epsom salts)
this calcutor turns out different results than my long lost 20 year old spreadsheet (P much lower than i was targeting), but it looks like this (add 60 ppm for epsom and 220 ppm SO4 from the epsom salts):

heres same formula on a different calculator (http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm). that grow formula would come out to 1400 ppm (2.8 EC), id end up using it at about 1100-1200 ppm for small girls. see i have the 75% strength listed as well:
