How to flush in soil?

Well you are a bit early for flushing unless your getting nute burn or lock, usually you don't need to full flush untill a couple weeks before harvest. If you are only 3 weeks into flowering then you still have quite a while till you need to worry about your harvest flush.

But if you need to flush all you do is put the plant somewhere where it can drain and put lots of water through it, enough that the water coming out the bottom is clear. That's all there is too it.
 
i read in this one site where it has grow guides and it says there that "white widow, b52.. in short all the commercial goodies needs to be wattered every day during veg and each two days during budding... sounds weird... can this be true..?
