Hydro, don't want to buy the whole line, got you.
Do this.
Buy "Oneness" 16oz for $13
Buy "Ginormous" 16oz for $16
Use Oneness during veg and the first half of bloom then drop it.
Use Ginormous during the beginning of bloom and halfway through bloom, it will be the only thing in the reservoir.
Ginormous doesn't have nitrogen, which isn't good to feed during hard flowering. The plant is supposed to use the stored nitrogen during that phase, so I like many others don't like giving nitrogen to flowering plants.
Although they claim "Oneness" is be all end all of One-part nutrients, I've noticed there isn't calcium in it.
Solution:
Buy Equilibrium the cal mag supplement. 16oz for $13.
Thats it. Everything a hydro system would need.
Calcium has to be added first to prevent other nutrients from getting locked out. I make sure to identify the calcium containing nutrient bottle for each line I use and w/e that happens to be, gets first dibs getting into the mix.
But I use both the Oneness in a DWC and I have a DWC testing out their Natural Line.
The oneness I treat like my synthetic hydro, no beneficial bacteria, no mychorhizal, just oneness transfer to ginormous. (My equilibrium I ordered has been on back order for over a month... Thats why that hydro store is not my favorite hydro store. I should have just ordered from my favorite one, but I don't know what came over me.
In my natural line DWC, I have Mayan Micro as my beneficial bacteria and White Widow as my beneficial fungus. The Bloom Natural has 10% calcium, so I have to add that first when making my bloom solutions. Makes me wonder why I even bought that equilibrium... Probably just to finish my collection or to have calcium to add to my oneness Dwc's.
The nutrients I started on and learned on were General Hydroponics. I would have tried their General Organic line, but people were telling me it was bad for DWC.. So i went with Humboldts Organic Line, which was "for best results use in soil". I figured they only say that because they don't want people going out buying their organic; dropping it in sterile DWC and having no benefical organisms to break down the nutrients. Organic nutrients have to be broken down by beneficial organisms for the plant to be able to uptake them. So if you are using hydro stay away from organics, unless you feel like breeding microorganisms.
