The buds in the pic are nowhere near ready for harvest. It doesn’t appear that they are even done with their stretch. 11 weeks at 12/12 but when did they start to show flowering. Sometimes takes a couple weeks. Then you can start counting weeks in flower. If it’s a known strain you can reference the breeder flower time to get a general idea, but they lie. The plant is going to grow up. When it stops growing up then the buds will start to grow out. That hay smell is from early harvesting. It may go away in a couple of months. Get yourself a 30-60x loupe on Amazon. Checking the trichomes is the best way. Clear is not ready, milky is getting there, some amber is ready. Be patient! It is a whole lot easier to harvest too early than too late. I would wager that no one has ever harvested too late without some extenuating circumstance. Also pics look like a bit of nutrient tip burn going on. As for curing, I hang dry till the outsides are crispy 7-10 days then clip the buds off the stem and put them in a paper bag rolled closed till they are at a smokeable moisture 7-10 days mixing once a day then trim and jar.
