Doing some more post-facto updating here...
Charlize didn't really respond in either direction to the increase in CalMag, so it could be thjat she was dfealing with fungus gnat stress (they're being impossible to get rid of) or just late life stuff. Her trichomes had gotten to about 10-15% amber by the end of this week, so she got chopped on 10/28, and I'll add a harvest entry for her next. Everyone else is rocking out super dense and bushy, fattening and clouding up on schedule! Home stretch! Daily trichome checks all around and we're just waiting to chop and hang. Maybe this weekend? Maybe one more week?
