Do not confuse yourself. Fox Farm has a fertilizing schedule for each of their line of nutrient lines and Cultivation Nation is one of their newer systems. It depends on which Cultivation Nation schedule you want to follow and that tells the grower which bottles and canisters to use. The '2 Part' is powder. The '3 Part' uses bottles of liquid. Two different Cultivation Nation schedules.Ok, I found it, "Cultivation Nation" 3 part" soil schedule. WTH is that and how is it different than the plain 'Soil Schd'?
The four bottom products are the same on both...
OK, I found it, Cultivation Nation is powder nutes and Big Bloom, Grow Big and Tiger Bloom are liquids with much, much lower NPK numbers, and organic? Is that the big difference?
Why would you buy both when you are just trying to get the NPK into the soil?
@AdaminCO provided the one for the traditional Fox Farm line of products that contains the Grow Big product. That set of fertilizers is what made Fox Farm one of the first and largest Cannabis fertilizing companies. That is the schedule that @Emilya is providing the help on. Do whatever you need to do to have just that schedule handy. Print it out or keep a link to it handy, whatever it takes. Trying to figure out how all the other systems work before you have had a chance to figure out the basic system will only cause confusion.
Remember that the Cha Ching has two other products that should be used together as shown in the schedule. There is Open Sesame and Beatie Bloomz. All three are in the purple section at the bottom and are intended to be used together as in if you are going to use the Cha Ching then you should also be using the other two mixed with water as shown on the schedule and used at the right time.But I have a jar of Cha Ching from years ago, so I'll use it!
Do not substitute the products in the purple section for the ones in the green. In other words, start using the ones in the green and follow through properly until the end for a successful grow and harvest. If you want to add the finishers, the ones in the purple then add those to your fertilizer line-up at that proper time. Do not stop the products in the green.
