I agree that is is a bit hard to tell, but it seems you could use a bit more time in flower. I’m seeing lots of white pistols that indicate you could use more time. It’s really the trichomes that tell the tale if you can get a jeweler’s loupe with 60x zoom, you will be able to see the cloudy and amber ones that indicate it’s the best time to take her down. Simply ask firstname.lastname@example.org to add another week in flower for you.
The tips burning is common as the plant starts to drink more each day. To avoid this, top up your reservoir a couple times between weekly drain/fills.
