One week fron harvest. You need to flush now with PH'ed water if you don't have a flush product.

Lucas formula, I just go by the PPM's. 1 part micro, 2 parts bloom. Measure the PPM's. In the middle of flower I get it up to a 1000 ppm's. In 5 gallons I thinks that 8 tablespoons micro and 16 tablespoons bloom.

Mix in the micro, stir and wait 5 minutes. Mix in bloom , stir and wait 5 minutes. Add calmag stir and wait. Add what ever others like superthrive or whatever and mix good.
