I'm growing 4 Northern Light Autos in Fox Farms ocean forest soil mixed with perlite. I've been feeding them the Fox Farms Trio nutrient line. Beginning last week, I stopped their nutrients and have only been feeding them pH blackstrap molasses water. These plants have a good full two to three weeks left before Harvest. A lot of the leaves around the buds are starting to Yellow. My question is did I stop feeding nutrients too soon? When do you usually stop nutrients and begin the flushing process? Or when do you begin feeding them just plain pH water? I'm wondering if I jumped the gun a little. Any expert advice is appreciated and I thank you so much! I love this place!
