Im taking it now you Feed once, then when it dries out water with plain water untill no nutes are in the run off?Right?
So you leech before your next feed basically? Does flush mean to put 3x amount of water to the size of the pot?
My reason is i thort you had to get rid of excess salts and wondered how often you should do this and how to do this....
2 times would be ideal i think. I only flush mine out once when there is 2 weeks left to flower, then i only use water.Do you know how often to do this in soil?
