I'll give it a shot
1)Bud Blood
This is a flowering stimulant. Basically you use this early in flowering, like right after you switch to 12/12, to help your plants create more and larger bud sites. BTW, they improved their formula on this and changed the name to "Bud Ignitor".
2)B-52
This is a B vitamin complex for plants. It does pretty much the same kind of stuff B vitamins do for people. It helps eliminate stress, keeps them chill and growing, etc.
3) Bud Candy
This is the combination of their old Sweet Leaf formula and Carboload together, with maybe a few other goodies I don' know. Useful for bulking up your buds and sweetening them.
4)Bud Factor X
IIRC this is the new form of their Scorpion Juice formula, which I believe was designed to crank up the plant's immune system to better fight off disease and pests.
5)Carbo Load Liquid
This is a carbohydrate concoction, basically liquid energy. Great for plants and microbials alike, but you have to be careful with this because the bad microbe thrive on it too. Great under good conditions, but gas on a fire under bad ones. It's now included in Bud Candy like I said above.
6)Big Bud Liquid
The gold standard of bloom boosting fertilizers. I'll vary my nutrient program from grow to grow sometimes, but I absolutely never grow without this.
7)Nirvana
Sort of an organic version of Big Bud. It's an organic bloom booster. I think Big Bud works much better.
Connoisseur A+B
Base nutrients, flowering formula, considered an "ultra-premium" fertilizer. It costs more and it's worth it IMO. Just be careful when you use it, it's very concentrated. Start out a lot lighter than the bottle recommends and dial up cautiously. It's a two-part (meaning there's two bottles that both get added to the reservoir to make one complete solution) and is designed just for blooming.
9)Voodoo Juice
This stuff grows roots. Crazy huge roots. Don't spill this on yourself or you might root right into the chair.
10) Iguana Juice (Grow And Bloom)
This is another base nutrient, one of AN's organic line. It's a two-part nutrient and has both veg and bloom formulas.
11)Sensi Grow A&B
Same kind of thing as Iguana, except it's not organic. Two-part base nutrient, both veg and bloom formulas. Sensi Grow is the veg, and there's also Sensi Bloom for flowering.
12)Rhino Skin
This is AN's silica additive, it makes stems stronger, promotes tighter internodes, and may discourage pests from attacking your plants because the silica reinforces the skin making it harder to chew through. Overuse can make plants hard to cut down.
13)Micro,Grow,Bloom
This is a 3-part nutrient that is mixed in different proportions for veg and bloom phases, so you don't have to worry about which bottles to use, just the proportions you mix them in. Not organic, but arguably the most flexible base nutrient AN makes. You can use the Lucas formula with this following the same directions as you'd use for GH's 3-part.
To grow you need base nutrients. That's it really. The plant will grow, mature, and ripen with nothing else. However, additives do make a big difference in the size and quality of your yield, so it's not a bad idea to use some.
The bad idea is to use more than you're comfortable with. My advice would be to use the Sensi 2 part base nutes or the Grow/Micro/Bloom 3 part with Big Bud as a minimum. Beyond that only add things one or two at a time so you can get used to how things work together.
Do too much too fast and you can get overwhelmed and end up with everything out of whack and hurting your plants.
