What about simply not nuting 3 weeks prior to harvest and have nothing to flush to begin with?

I am not advocating this, but rather, asking why not?

If you flush one week prior to harvest where is the plant going to obtain its calcium and some other minerals it needs? MJ simply cannot and does not store these minerals in the cellular structure of the plant.

From where would they come?...just curious
HARDDON Reviewed by HARDDON on . Is it necessary to flush? Is it necessary to flush my potted outdoor plants if I've been using Foxfarm products all along? For the last couple of months I've been feeding them Big Bloom & Tiger Bloom along with a worm casting tea. I know if you use chem nutes you should stop feeding two weeks prior to harvest. Rating: 5
