Flowering liquid fertilizer 3.7.5

3-7-5 is fine for flower.. I would add K of some variety if you could.. Lots of things can add some K ask you local store.. But a ratio of 3-10-10 can be fine. I mean people flower in 20-20-20 so just the important part is not too overdue it in any fashion. ! tsp a gallon of water sounds good to me for molasses(simple carbs/sugars). Humic or even fulvic acids you want to be careful with so I'd consider doing exactly like the bottle says ( but even try 1/2 the amount they say to use for the first time) or full strength on only one plant. Lean towards the side of caution with Humics.. Humics will increase intake so you just don't wanna overdue it... See the key here is Balance with the exception of lower-light amounts of nitro. But 3-7 is a comfortable number if you are not nitrogen saturated.
