FF- hmmm not quite sure I am getting you here..

As far as your question..I usually begin to add my carb boosters "sweet" or molasses or both the first day of 12/12 that I feed/water them. Some people begin using it from the beginning of a nute schedule in the veg stage. I know that my hydro store guy does. I don't though. I just wait until flowering. As you can see with no adverse effects on yield.

good luck,
Elway
