Humboldt has a plethora of feeding schedules.. at the hydro shop I tested the ppm, 1ml per gal , for each of the products they recommend for hydro. Part a&b were at 30ppm per ml a gallon each, the sea mag was 20ppm 1 ml per gallon and the Ginourmous was around 70ppm/1ml gallon.... The "hydro" chart shows to use per gallon 4ml each of a&b, 1ml of SEA MAg and 1ml of Ginourmous...for first week flowering... next four weeks the part a&b are only raised to 5ml a gallon ok ,, lets add it up.. 50 gal rez.. part a=120ppm , part b=120 ppm , seamag=20, ginourmous =70,,, for a whopping total of 330ppm.... and thats what my ppm meter went up after adding these amounts!.. . The hydro store guy and the company rep said not to worry about my ppm because these nutes use amino acids and others use salts that raise ppm .. and that all the nutes are available for my plants... needless to say, I am concerned.. One chart of theirs shows this formula to be in the 900ppm range , with addition of 1ml of their sea cal ... Im sure the sea cal only raises the ppm a little.... Looking for any opinions before i ruin my plants at such a vital time.. 2nd week of flower.. Thx, Frogster
