Miracle Grow put on top of soil to fertilize?

Is 2 weeks enough time to flush the plants? How often should I water them while flushing?

is there really any point in buying that though? I mean theyre staying in the ground so any mix added would just go on top like the Miracle-Gro did.

no u dnt have to buy ne thing, a thin layer of MG soil is really not gonna make much of a difference, and if ur not using nutes theres not much need for flushing, just use the molasses the last 2-3 weeks of flowering

Ive been feeding them with a fertilizer once a week

then i would flush 2-3 weeks prior to harvest and then use molasses the rest of to wat through
