I made some fresh frozen bubble hash with the trim, a bucket and my hand. Nothing in the 220u bag and some for the 70u and the 38u bags.
Very beautiful buds, they are sticky af and it taste like a sweet mango.
In curing for 3 weeks
This is exactly the time when you want to do that - actually, the third week of flowering is when you generally want to start that sort of thing - so since you're in the 4th week, go for it! The grow is looking great!
Good luck!
