Hi. I have Bionova Vitasol but until today I have not found a clear explanation on its role and its use? when, how and why do you use it? thank you in advance.
It's a potassium supplement that supposedly increases nutrient uptake. I couldn't say whether or not it works, but I would start after the second week of flowering.
Diamond Nectar uses humic acid to basically achieve the same thing without the added potassium.
