Does flushing with clearex wash away nutriets too

I'm building a soil with lots of bat guano and worm castings. Would flushing heavily with clearex in say week 2 or 3 of flowering affect those nutrients, or does just wash away salt build up? Thanks.

if you are building a soil and not using bottled nutes, HOW could you have a salt build up?
if you grow a plant properly, it shouldn't be in the soil long enough to build up salt.

I'll be feeding with some bottled nutes on top of the guano and casting. Balanced nutrients until flowers appear. Would like to then flush and begin feeding a more heavy P nute. But the question, would that flush affect the guano and castings I'd added to the soil. Thanks.

Okay, thanks for that. But I don't intend to go that high on P and low on N. Actually, that's why I'm asking this question, as I'd like to know if the clearex might hurt the worm castings (N) during flowering.

I dunno but out of curiosity, why not just use ph'd water?

Probably will. Just curious about the clearex.

Here's my thoughts on it. I've only used bottled nutes combined with organic once when I first started organic. I just flushed with ph'd water. No salt buildup (at least not that I could tell).

I don't know if the bacteria will break down bottled nutes or not, but what I would do is repot just before flowering and add more organic P to your soil. They will still have a decent balance as long as you add a little N, but then there's no chance of salt buildup.

Your roots are going to expand approx 2-3 times what they are during flowering. Just makes sense to repot with fresh organics. Just my thoughts.

I don't think you want to flush a organic soil, even water only. The flush additives contain sugar. A long time ago I read you can make your own:


But, I don't think flushing's necessary/desireable for most people unless they feed synthetic nutrients, and feed heavily.
