hi there i have just purchased some hoof and horn to use as a secondary nitrogen source for a long flowering 16 week+ sativa. My main nitrogen source is guano but i thought the plant would benefit from a little bit of slow release nitrogen throughout the long flowering cycle - many people in the usa use feather meal for this too i beleive.
anyway, has anyone ever used this or can advise me on an application rate?
thanks,
V.
