Looking for advice for the last few weeks

Probably closer to 4 weeks. It's a 35% sativa, so they normally go 9-10 weeks in flower. Don't flush and if you must then only flush for the last week. It really doesn't do anything except give you the chance to starve your plants. Whatever you do, don't flush too early or you'll hurt potency and yield.

Lookin good mate, just keep an eye on that under carriage, looks pretty crammed. Make sure you get plenty of airflow in there (osci fans) and keep the humidity below 50% ideally and temp 26c or lower, that's how I like it. Doesn't matter how low humidity goes in flower. Good luck with the rest of it
