You should consider using raw salts. It sounds complicated, but it's really no more complicated than mixing those bottles, and WAY cheaper. If anything, it's a lot more straight forward. Snow storm, for example, is just diluted potassium hydroxide (KOH). I just add KOH directly to the reservoir in flake form.
You can get K2SiO3 (potassium silicate) in raw salt form for a lot cheaper than diluted bottles of potassium silicate (like dynagrow's version). Bloom boosters are just KH2PO4 (monopotassium phosphate). I just use potassium hydroxide flakes as pH up, however.
Don't know where to start? Start at Mix #15!
N : P2O5 : K2O ratio = 1 : 1 : 1.9
K : Ca : Mg ratio = 1 : 0.6 : 0.19
Ingredients per 10 gallons of water:
KNO3 - 8.47g
KH2PO4 - 9.81g
Yara 5Ca(NO3)2 . 1NH4NO3 (double salt) - 25.5g
MgSO4 - 15.4g
KOH - 2.88g
FeSO4 - 0.942g
Na2B4O7 - 0.234g
MnSO4 - 0.233g
Na2MoO4 - 0.005g
That will put 10 gallons of water at about 1.3mS/cm.
If you don't know what one of these chemicals is, google will tell you.
All of the ingredients in bold can provide 100% of the macro nutrients for any hydroponic formula. They are all extremely handy to have around, and so cheap it's hard to justify not getting them. Yuo'll never need "bloom boosters" again, for example. Just add more KH2PO4, the main ingredient in bloom boosters, and balance the pH with KOH.
I follow the complete floranova expert drain to waste schedule. You can find their feeding schedule online. The expert line includes rapid start, floralicious plus, diamond nectar, flora blend, flora nectar, koolbloom powder, koolbloom liquid, floranova grow and bloom..
I also use silica to raise my pH in my nutrient solution instead of ph up.
I alternate full feedings with a feeding of only cali-magic, hygrozyme and snow storm. This mixture requires no ph adjustment when using RO water
I use RO water for both feeding types and I feed/water every 2-3 days depending on how far I am into flowering. I might water every 4-5 days early veg
