ive tried many nutrient lines over the years,, from 2001-2003 i did side by side comparisons on 2 4x4 flood tables, same strain, same lighting,conditions, everything the same exept the nutrients...many were 3 part nutes, what i found was they all work,, once u get the mix wright or dialed in to your strain you get healthy happy plants.. i liked general hydroponics and plant life 3 part nutes best,followed by fox farm, dyna grow, and botanicare. B.C,and advanced worked well but i had alot of problems w yellowing and ph stability till i got the mix wright.. in 2-3 years of side by side testing i found the 3 part nutes just wer not cost effective,,i wanted healthy plants w big yields, potency all at the lowest cost possible..for this i liked the 1 part grow, 1 part bloom, or all in 1,, like foiliage pro, flora nova, and maxi series... all 3 work great, are easy to use and grow healthy big plants,, so it all came down to cost..maxi is by far the cheapest, but cheap in this case did not mean its not as good,, it grows just as well as the other 2 at a lower cost per run.. all my tests wer done w base nutes only, no bloom boosters or aditives.. i did seperate testing with aditives and bloom boosters after i knew the average yield and quality you get w the base nutes only..most base nutrients contain the npk and micro nutes to get healthy happy plants w/ out additives or boosters,, most boosters and additives in my opinion are a waste of money,, however silicate , kelp, and vitamin b.all have a time and place...i no longer have the room, time, or money to do testing and there are alot of nutrients that i havnt tried or even heard of back then,, i hear good things about canna, j.r.peters, and more that i have not tried..so as long as u grow, to each his/her owne, whatever nutrient line you use, as long as your happy and your plants are happy, that is the best for you!!! if you use boosters or additives and think they help,, use them,, it sure doesnt hurt..
grow well and be well to all!!
