Using humboldt honey during veg really only has advantages if you are using mycorrhizal. Then it will feed them and they will establish bigger root systems. So since you are in soil.......humboldt says to use 1ml per gallon from the start......then you move up to 2ml per gallon in week 2&3 of bloom, week 5&6 5ml per gallon, week 7 10ml per gallon, and for final flush week use 15 ml per gallon. But in all honesty....I only used it for one grow because grandmas molasses gives better results. Just my opinion
