When to flush autoflowers?

Heisenherbstarted grow question 3h ago

So many people give the advice to flush before harvest but how do I know when to start flushing, how the flowers should be looking? Im at week 8 now, autoflower. They dont seem mature enough but when to start overdrive and then the flushing? Thanks

Agree with Hashy, Flushing is a tool to correct an issues in the medium, not a practice for better buds. that's mostly on genetics.

I don't flush, but just water as normal for the last 2 weeks without Nutrients. You probably have another 3 week or 4 before yours is finished. Wait another week or so before scrapping Nutrients for just water. If you have been feeding a lot then that last 2 weeks there should be enough nutrition in the medium to last to harvest.
