If you are flowering,you should be using a high P rated fert rather than the 20 20 20. If you use a bloom fert like shultz. You should mix it at 1/2 strength.Use it every other watering or 1/4 and use it every watering.You will see the bud sites starting to progress a bit faster.That is waht they are needing at this stage.I use this at 1/4 strength for my cuttings as a foliar feed.

Ga Grown!
