Well you're starting out right. You have a nice list of gear and you're asking the right questions and you arent scared to do some research. You're gonna do ok.
I didnt check out those links so I dont know if I'm saying stuff you already know but..here are my views on a couple of points. Oh..and I'm not familiar with the FF nutes or medium.
SO..there are several ways you can go.
You can get soil and go organic.
Soil is..or should be alive. It should have organic matter in it that is being broken down by critters like enzymes, bacteria, fungus, even insects..and turned into "nutrients" or elements that the plant can use. I'm gonna put on my asbestos suit for this next part cause I'll probably get a good flaming from the organic guys but..if you ask me...with organics..or soil..you have less control than with non-organic and soiless or "mediumless" methods.
It's harder to flush (rinse) should a problem occur, you have a hard time knowing what's exactly in the soil, and, hydroponic methods usually promote faster growth.
NOT to say that you can't achieve stellar results in soil organically..just if you ask me, I keep organic growing outdoors.
Soil is more forgiving than hydro though or can be..and can also be a bit less of a learning curve...not that you can't go pretty deep into organics.
Another option is to go soiless with something like coco, sunshine mix, peat... Those are mediums that contain no nutrients. I'd say though that for what we do, you could add pearlite to all of them...
ANYWAY..since those mediums have nothing in them nutewise, YOU have to supply all the nutrients for the plants in your watering solution. BAM..you're doing Hydroponics. Hydroponics doesnt mean you're growing in a lab with no dirt..it just means that you're adding nutrients to water and feeding your plants that way.
It's easier to flush some of these mediums than soil and (buildup and depletion aside) you know a little better what your plants are getting.
Since you have no beneficial "critters" in the medium though, the door is left wide open for bad critters to get in.
When growing organically, nature's balancing act helps to take care of a lot of the nasties with the good soldiers.
Like soil, it is quite forgiving and imo is a great method to start learning by. These are inert mediums with nothing in them so you can do either organic (with organic nutes, enzymes, and beneficial bacteria and fungi..) or non organic with liquid or dry nutes.
Then there's what you could call mediumless. Full blown hydroponics like UC, Aeroponics, DWC to name just a few.
Those are pretty much where your roots are suspended in the air or water with a small bit of medium like lava rock, rockwool, expanded clay..just to support the plant.
There is very little tolerance for error in these systems but once you know what you're doing the results can be staggering.
Now on to the nutrients. Since I'm not an organic guy I will only tell you a bit about non-organic nutrients.
Typically, with whichever method of non organic growing you're doing, you have a base nutrient "diet". It can be a 3-part system or two or even just one.
The 3-part liquid usually has 3 bottles with names like grow, bloom, and micro. Depending on the stage of the plant, the bottles instruct you on how to mix the proper ratio of nutrients. The plants want higher nitrogen in vegetative stage and a bit less in flowering/bloom stage etc. These "base" nutrients supply everything the plant needs (well..if it's quality nutes). They display the N-P-K (Nitrogen, Phosphorous, and Potassium) in large print usually and on the back of each bottle it should list all the other micro and macro nutrients.
The base nutrients are ALL you need to grow WICKED bud.
BUT...there are a zillion additives out there seemingly to either just confuse you or just to pry more $ out of your wallet or both.
MOST people use at least one or two additives and some use a TON. I've never found it to be...or even read anywhere (except for in advertising) that using additives make a HUGE difference. YMMV I guess.
There are additives that boost certain elements, some that are supposed to add more crystal, make HUGE buds, make it taste sweeter, additives for flushing, to keep your plants shorter, taller...you name it.
Then there are additives that are kinda like conditioners. They can do things like keep your solution sterile, make it have more oxygen, add enzymes, bacteria, fungi...
This group of additives can be very beneficial...not together all at once but..that's a whole nuther lesson.
SO...If I were you, (I'm not..I know) for starters I'd choose a method (I'd choose method 2..sunshine or coco...) and just get the base nutrient line from whatever reputable manufacturer you choose.
Keep reading and watching and learn as you grow.
Once you start getting the hang of it, start trying some additives and maybe try increasing the difficulty level by implementing a more advanced or involved method...or just keep doing what you know.
Either way..I wouldn't recommend that you run out with a big shopping list and coming home with a cart full of bottles of blast this, candy that, Jacks magical beanstalk jiuce..at least not right away.
Hope you got at least a grain of something from all this.
PEACE and good luck man.
