thanks Stinky. yes it is unsulphered as I had read from you before I ever started using it. I guess if I can't figure it out, I will just continue as I have seeing that the final product has never left me unsatisfied. far from it actually. I have added garden lime as I always do to the soil for a mag cal buffer and it always seems to work.
I will be adding molasses to one of my plants today seeing she is a month in flowering. I have been using sweet on her with no yellowing thus far. I guess I will see after today if the problem continues. I will take before and after photos and post the before photos today and then keep everyone posted so maybe we can get to the bottom of this...
