You could, if you must, give a very small amount of a well balanced nute formula, with lower N and higher P&K levels...like 2-4-5 or so....not set in stone. I, myself would not nute that plant. Maybe some unsulphered molasses. I put a dollop, about a teaspoon, in a gallon.

Right now the plant is putting everything it has into flowering. It does not need the sun leaves as much now, especially the low ones not really getting enough light. Eventually on some species all the fan leaves will turn very yellow and the buds will be green. It is nature's way of saving energy and being energy efficient.
