7-14 days till chop from photos ;)))
And i do believe in flush and i do it if i can. Usually i am limited to weather, so if its not summer, i just go plain water with soil grows for 2-4 last weeks ...
If you're on Day 5 of flush, you can go straight to chopping her without any worries. Some people like to flush, some don't think it's necessary - but you've already done it so go chop!
Good luck!
Looks good, quick FYI, flushing is a myth and does not add anything to your grow/end product.
If you chopped end of week you'd be happy with its results, give it a nice dry and cure.
Good Luck!
