Is it ok to flush a day after feeding ? I gave them the wrong nutes my first feed so I just want to flush with PH water and see if that helps? Or should I flush with the right nutes? I use foxfarm and I used the Grow Big Formula , it is for vegging but later in life!! the Big Bloom is the one for newly transplanted veg stage, Thats the one with guano and earthworm casting ! Should I flush with a low dose?
