No, Southern Ag Chelated General Purpose Minor Element Nutritional Spray is not labeled to be used on seeds, it is used at the first signs of the deficiency symptoms so plants need to be actively growing first.
We do not see why you cannot mix the Southern Ag Chelated General Purpose Flower & Garden Nutritional Spray with the Southern AG 10401. However, we do recommend doing a jar test first to see if they mix well together and reviewing each product label for any tank mixing restrictions.
