Molasses

I use molasses quite often. I mean unless you have too much nutes, I don't see why not...

Like, for ghetto "goto" cheap, effective sort of supplement I'd use would be molasses, yoghurt/milk and perhaps something like lemon juice (or another citrus fruit).

"The plant produces this on its own and uses it as engrgy. It can be beneifical to add in the later stages of flowering giving her more energy to help flowers get bigger and ripen faster :) " Nonsense. The plants don't produce molasses, it doesn't make potassium, magnesium and shit. The plants produce their own derived sugars, mostly distinct from molasses.

Molasses is a good general addition/feed/supplementation as it contains a large amounts of varied elements and can aid microbial activity. In terms of common elements it provides decent magnesium, potassium, particularly. You can use it fairly regularly, imo. Just don't overdo it.
