I started using Bat Guano, Jamaican no less! 1-10-0.2 . I use it as a top dressing about 1 T on the top of the pot and then water it in. It does seem it help out. Buds on the plants are so very happy. The plants are clones that I took off of flowering females. Number one is a California Skunk and number two is a Afghan. They seem to love it. Lots of buds.
