can blackstrap molasses be used with this product?
Blackstrap molasses mixed into water after you top dress would be fine to use.
Is there an approx. NPK ratio for this mix?
We do not try to get a certain NPK ratio for our top dress mix. It is more about providing all of the necessary nutrients for the worms and microbes to digest to make what the plant needs bio-available in the soil.
If you would Love to see Snow Fall in Summer on your Budz,... Then the Top Soil Cover Dressing is for you. I attached a photo of a 2F2B StarDawg. Still have a month left and look at the crystals already,.... ;)
