Should I start flushing?

blind taste tests show ppl cannot discern once you remove confirmation bias from equation. analysis proves that flushing does not change what constitutes flower -- mineral content and such is all the same and in same proportion. Do you ahve a toxicity or major pH issue? if not, there is no reason to flush. It's an invasive tool that should only be used for good reason. Stripping nutrients from substrate can only slow growth, not improve it. Also, severe concentration shifts can mess with a plant's chemisty.. it depends on osmosis and diffusion, and if you throw a wrench into those dynamics, it isn't a positive for the plant. If water outside the cell has significantly less dissolved minerals, then that will cuase excess water to flow into cells while trying to reach an equilibrium concentration on both sides of semi-permeable membranes. real physics... not made up bro science. everyone can have their own beliefs, but that doesn't make them true. When faced with incontravertible evidence (like mineral analysis) you take your lumps accept better knowledge and move on. if it's personal, that's a red flag. It's also a red flag to claim various hypothesis without ever testing them... then when they are tested and proven wrong 'they' just make up more reasons why it is useful despite never mentioning those reasons before... it's like trying to have an adult conversation with a 5 year old sometimes. They made soemthing up that sounded science-y and it stuck... now, the reasoning was put to the test and shown lacking.

It's completely up to you. Some people flush for 2 weeks, others for 1. Some don't flush at all! If you have a flushing product you go by the recommendation on the bottle. If it's just water I'd probably go for 2 weeks.
