Back to reality here, I'll give you a some facts:
If you use RO you will need Cal-mag supplementation with most hydro specific base nutes.
If you don't use roots excelerator your plants will be fine, but with, the roots explode in half the time.
People on boards will get on the 'no additive' kick for a grow or two, they will be all bragging etc. 2 grows later they are back to using additives, just not bragging so much anymore, giving everybody on the boards the impression that they must be crazy if they are using any additives.
I've grown without additives and with, and form my personal experience with HYDRO, I can unequivocally say that: LESS SHIT GOES WRONG WITH SOME BASIC ADDITIVES!
So how about some people that actually grow Hydro with NO additives showing us some pics of their grows, that would be a lot more helpful then this your stupid, no you are stupid bullshit!
I would love to drop the additives out, but I will not do it on the word of someone who grows in soil.
