GF takes up to two weeks to start working from a top-dress, meaning that you would need to top dress the soil as soon as the plant pokes out! Is this a sponsored grow? Because if it is you should probably reach out to GF in their thread for advice:

Twice I've been admonished for offering non-sponsor-product advice in sponsored thread. But in a word, the plant is hungry!
