This is bad advice, DO NOT add PK 13/14 2 weeks before harvest. PK 13/14 is designed for the heavy fruiting/flowering stage of plants. In a hydroponic system it is generally added at weeks 5,6 and 7 of a 9 week flowering strain. You stop using it 2 to 3 weeks before harvest depending on your growing medium.

If you are growing in soil it is slightly different, according to Canna you add it at week 3 or 4 of flower. Here is a link to an official Canna Terra feeding schedule.

You should be able to find out more info on the CAnna website, but you have to register.

I use Cannaboost but only because I got a free sample at a trade show. It is very expensive and is supposed to increase yield, but you will probably be better off investing your money elsewhere until you have the rest of your setup fine tuned.

If you need any more advice it would be a good idea to give a bit more detail about your setup.
