That plant is over watered and over fed. Yes good soil does buffer itself. There's really no reason to be giving molasses.Youd be better off top dressing some EWC a few times to keep the soil live and happy. Also Big Bloom is the only full organic of the Fox Farms trio, you can actually give the Big Bloom at full strength. What soil are you in exactly.
Back off on watering and space out your feedings. If your in Fox Farms ocean forest soil get some cal mag or epsom salt, you'll need it.
