Even Organic nutrients I still like to see them flushed but that's just me. With Organics it's not as important as if you are using non-organic nutrients but still it's a good idea so you get the full flavor of the flower.
Zandor Reviewed by Zandor 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
