I have done it in the past, but never in a side by side with one plant without Molasses, so I can't say if it helped or not.
I couldn't tell any Molasses taste like some say, (which I didn't think I would anyway), but have been Chatting with SOMEBEECH a bit, and he has used in the past I think, and we agreed my last week or so I would water with just Molasses since I recently burned her a bit.
But, I have been giving 1 tsp/ gal every other water throughout the grow since I started feeding at day 25.
The only thing I'm not sure of, is I remember reading that the Molasses has a tendency to drop the PH more than just nutes will.
And Jpeg, ya, he's got some good stuff going on.
Been busy lately I think, but I follow his threads also.
