i spent a few years running side by side testing of base nute line ups in 2 4x4 f&d tables w rockwool.. the reg 3 part advanced was not in the top 5 even.. gh maxi, nova, 3 part, plant life 3 part, fox farm, and more produced far better results.. recently i tried the ph perfect and it worked well, way better than the reg 3 part by an..not the best, but not the worst..it may be the answer for newbees..
but if you know what your doing and your point is to get the best quality weed, and best yield per cost of nutrients.. gh maxi grows great weed and large yields w a very low price tag.. in hydro, in rock wool, or grow rocks,, it just works.. for people who make their own teas, or aquaponics, there is NO comparison,, its apples to oranges.. as far as store bought nutrients go maxi is king or was king,, i did testing back in 2003-2006 since then there are many new nutes i havnt tested that may be great idk..i no longer have the time or money to continue testing but once in awile i try something new as i did with the ph parfect,, but im back to gh maxi and nova,, for me , in my water, they work best and im very happy with end results and ease of use...
we are all growers and stick with what we like,, this debate could go on and on with nobody changing their line up.. if you are happy with your grows, stick with what u like... i mean isnt the point of growing just doing what we love and enjoy?? i respect other growers and what ever they use to grow,, its just your preference and opinions.. grow well and be well to all growers,,lets learn from one another, respect each other, let growers unite, not fight!!!
