I've got a problem. I am growing in soil and have been using Earth Juice ferts (grow, bloom, and catalyst). Last weekend for my usual nutrient cycle I added a mild amount of molasses to my feeding, 1/2 tbsp to gallon. Ever since then my older fan leaves have been turning bright yellow (think bananas) and then either shriveling up or coming off with a gentle tug. Should I flush? Is this a result of toxicity or deficiency? Am I just assuming this is because of the molasses? I haven't really been having anything like this happen until I used the molasses. I just started week 6 yesterday and I know that yellowing is natural towards the end of the flowering cycle but it just seems like this is an excessive amount of yellowing... Any input would be appreciated.
