Fulvic acid, humic acid or amino acids will help and will actually do something great. (rather than BS molasses, which does nothing).
All 3 acids if you are really keen.
Add a P/K booster, a bit of calcium/magnesium and some trace elements and this will also help.
Feeding with Flora Nova one part Bloom made by GHE, is almost guaranteed to produce superb results too.
And whatever you do, do not defoliate!!!
Your plant needs every healthy green leaf it has to produce the energy to grow her biggest and best flowers.
Just remember -
maximum healthy leaves = maximum energy = maximum growth and maximum health.
