Eight weeks from sprout, four to harvest.
This week the leaves started showing more signs of nutrient deficiencies so I top dressed with time release nutrients a few days earlier than planned, and also started supplementing with liquid nutrients in the water at the doses recommended for this time in the grow cycle. I hope I'm not overreacting as I understand it's normal for leaves to yellow and fall off during flowering, but I didn't experience this with my first grow so I'm erring on the side of supplying extra nutrients.
The flowers are still looking quite healthy and filling out nicely.
