Tropicana Cookies Autoflower

Bumped up the amount of CalMag and FloraBloom this past week trying to save the plant on the right. Unfortunately nothing seems to help it. The other two are going very strong. Very smelly even with carbon filter, much more than my first grow. Looking to maybe harvest the two on the left sometime late next week hopefully. About 60/70% of the pistils have turned orange on those two with only about 30% on the right plant.
