I use the same MG product well the blood meal. The NPK numbers will not support cannabis throughout the flowering process.

These products could support growth to the 2nd week of flower. Honestly I read this a few times that said that you need to reduce your phosphorous levels after the 1st or 2nd week of flower. They said that this could prolong the flowering period. But I would take this advice with a grain of salt as I haven't heard this from a valid source.

Anyway I would buy the Marijuana Garden Saver if you choose to go the MG only route, this will help you identify possible deficiencies that might occur.
