they look good, and on schedule.... yes you can mix the molasses with MOST nutes..... I would also use 1/2 strength molasses with select waterings, like the watering after a feeding, if another feeding doesn't come directly after the watering....... but thats more of an outdoor thing where water/nutes leeches faster and transpiration occurs in higher concentrations. Indoors it depends on what nutes you use... like slow release as apposed to readily available organics..... for example FF TB (Fox Farms Tiger Bloom) is a slow release nutrient that is organically based with chemical additives like boron (which simply means the compounds were isolated and thus concentrated before mixing in with the organic base of sea weed kelp etc., and Bio Bizz Bloom is an organic nutrient solution concentrated (concentrated by evaporative means, rather than compound isolation) for immediate consumption. Bio bizz bloom already has molasses in it to encourage the p and k uptake from the readily available organic nutes..... FF TB has no molasses in it, so you could mix some in with the nute feeding AND water with molasses in the water which will encourage the roots to break down the slow release nutrients and use them faster before they are leached out of the soil. I would not mix molasses directly in the same solution with chemical hydroponic fertilizers.
We are using sensi bloom A & B, which I dont think has molasses in it. Altho, I am unsure of the organic part. Sp maybe it would just be safer to not add it to the nutes and do it with the reg watering.
.... sometimes less is more
