here ya noob, this is how you flush
flush the soil with water 2-3 times the amount of soil you have (5 gals soil means 10-15 gal to flush), you let all the water run out the bottom.
This removes all the undissolved salts and nutes in your soil do it about every 3-4 weeks and 2 weeks before harvest.
Add 1 table spoon Black Strap Molasses to the last gallon of water + your nutes and a cap of hydrogen peroxide and your all set.
