Hello,
I sent CANNA Nutrients a message asking them what products they recommend to pre-treat rockwool. I assumed that it would be fine to use a 1 ml/gal of each Canna Coco A + B (since ill be growing in Coco) and pH treat the water to 5.5. Also, I asked what feeding would be best after the smaller 2" cubes were transplanted into 3" cubes. I've never used rockwool before, and I just assumed this was the process based off my observations. Also I was a little unclear on the PK 13 14 application and how/when it should be used, so I asked. Here was their response:
Grower,
First, we do not recommend any rock wool pre-treatment products. It is important that they be treated to lower the pH, we just do not recommend brands.
Second, going from a 2 inch cube to a 3 inch cube is a waste of steps. Get a good root system on the first cube and go either directly into a 2 gallon or smaller container, or drop them into a 4 or 5 inch container of coco then into a 3 gallon or bigger container once it has good roots. It is important to get the roots to convert from RW to coco soon as possible.
Finally, the ideal way to begin using PK 13/14 is to start using the product when you see the plant's vegetative growth slow and the terminals begin to change into flowering structures. Then use the product for about 3 weeks. The next crop you can begin to shorten the application period and move the start and stop dates around to ultimately arrive at a 7-10 day interval of application that saves money and achieves maximum results.
Ok,
Their response confused me. I guess going directly to coir makes sense rather than a larger rockwool cube, however their PK 13 14 recommendation was damn confusing. I always thought that the PK was supposed to be applied either in the 3rd or 5th weeks, but the part about 7-10 day intervals makes little sense, especially when he states, "a 7-10 day interval of application that saves money."
Anyways, I was a little confused when I got their message, so any advice would be appreciated, especially if you have experience with Rockwool, Coir, or Canna Nutrients.
Thanks!

But do you think Pk 13/14 is still necessary with Jack's Pro Hydroponic 5-12-26 since it already has a high content of P-K.
