Nutes and soil

just a quick question to you all? I'm in soil I give nutes with every water but not at full strength. Do you all give them a flush out before starting to flower????

You should be monitoring the runoff ppm. That would indicate whether you need to flush (or should've fed with more runoff each time). I try to keep mine between 1200 and 2000. As it approaches 2000 or higher, I feed with more runoff (and./or reduce strength).

If you don't know the level of salt buildup, it wouldn't hurt (much) to feed for 50-100% runoff. I wouldn't do 300% flushes without there being a specific reason.

What az2000 said... honestly, I never flush. My buds never have a weird taste and they're always nice and tight nugs. Just saying.
