okay well my plants are in 4th week of flower and im going to add my DNF bloom fortifier before bubbling, but i want to work my way up to full strength, i already did try doing the math for 50% of the bloom fortifier but on the label it says 5L per every 22L for full strength but i only use 7L to water mine. so what i did was 22L/7L=3.142 but after that i do not understand how to do the math but i did 7/3.14=2.20 (rounding) so assuming that 2.20ml is full strength for 7L so i just divided 2 by 2.20 to get 1.1ml for 50% but has anyone else had this problem as well? could anyone help me out ive been at this for awhile
