can you use molasses with hydro i dont have time to read all this post plz help you can just quote the parts that talk about it if you want sorry im really in a hury
Simple answer, no.
Molasses is not utilized in its raw form by the plant. In soil, microbes break down the molasses into nitrogen, potash and other nutrients, which the plant is then able to use. As you are growing in hydro, you do not have the soil microbes that would use the molasses for energy, and which would then convert the raw molasses into a usable mineral form for the plant.
If you are growing in soil, molasses could be beneficial, but if you are already using a full support chemical fertilizer it is unnecessary.
As to molasses affecting taste in a soil grow, I am not sold on that. I think some people are thinking the sweet taste of molasses is somehow transferred to the pot plant. The pot plant is not sucking up sweet molasses like a kid with a straw. If it were not for microbes using the sugars and breaking the molasses down into component mineral forms, the plant could not use the molasses at all.
