I've been doing the hydro thing about 12 years now, using GH three part liquid. I came up with my chart by using theirs and the one gallon ratios and multiplying by 17 as I'm using a 17 gallon reservoir.
Like other companies they may have modified their chart per gallon, as mine hasn't changed.
I've got paper copies that I work off of when mixing my nutes. Please feel free to go to my links in the signature to see the results. I last harvested the Acapulco Gold. The Golden Tiger and Blueberry are still in veg.
I just follow the chart.
My Golden Tiger just got it's first 17gallon reservoir after being moved from a little 2.5gallon DIY DWC. Going off my old chart, 180ml Grow, 135ml Micro, and 45ml Bloom equaled
Early Growth in my 17gallon reservoir.
I'm not looking for guidance, just comparing practices. For the most part, I've got it down pat. ACE warns in their Golden Tiger write up go lite on the Nitrogen and to to that, would provide less other micro nutrients. That's the rub.
