So I'm using this soil for the first time do you actually have to give it additional fertilizer with this soil or can you use it just by itself? Or what fertilizer works best with this soil?

It will feed decent sized plants for two weeks.

U can go for a month without adding anything, every other watering you can add as a preventing measure 1 teaspoon of calmag and 1 teaspoon of Epson salt to a gallon of water

I hear Dolomite lime and Epsom salt help out a lot, but never tried. Brown dirt warrior uses it.

I'm a newby with no prior experience, & I've grown 5 plants with it & I was really pleased. I didn't add anything for the first 2-3 weeks & then I added FF Grow Big, Big Bloom, and Tiger bloom.
I'm on my second grow now with a different light set up (spydr600LED) & I'm gna add FF dirty dozen this time as well to try to increase my yield... GL

IMHO FFOF is too hot for seedlings on it's own. I would add a good 30% perlite and not feed anything until about 2-3 weeks AFTER transplant. Then start your regimen at 1/4 strength and progress up 1/4 strength at a time until full strength.
Personally I use FFHF and prefer it over FFOF, but to each their own.
Good Luck and Great Grow!

I always add 1 spoon of epson salt and 1 spoon of dolomite lime per gallon of soil straight to my soil mix just as a prevention method.

What exactly do Epsom salt & dolomite lime do??? I see people talking about them for various things but I don't understand exactly what they do....

Epsom and Dolo? Mg overload....Dolo has plenty of available Mg...Adding Epsom straight to the soil isn't a great idea either. Dissolve in water first.

Epsom supplies Mg and S.
Dolomite is a liming agent and has plenty of Mg available......If amending FFOF all you need is about a good handful (1/2cup) per bag and mix in well.
FFOF and FFHF always seem light on liming agent and Mg in my book.....pH will slip and Mg def's occur regularly.
FF soils tend to carry soil borne pests like fungus gnats.....

Oh, ok.... Thanks for the info! I'll try it next time
* Epsom is fast-acting magnesium and sulfur. It contains 9.8% Mg, 13% S by weight. 1g in 1gal produces 26ppm Mg and 34ppm S.
* Dolomite is carbonated calcium and magnesium. It is slower acting. Dolomite contains those carbonated forms at a 1.2 to 1 ratio (and breaks down to produce 1.6 to 1 elemental Ca & Mg). That helps you know if you're getting dolomite. There's a lot of confusion in how different lime is named. Look at the label. (You do not want hydrated lime, which is all oxides and virtually no Mg.).
Dolomite is amended into the soil to stabilize the ph over time. It also provides mg/ca as a side benefit. But, slowly. People tend to use 1-2 Tbsp/gal of soil. I do 1-1.5.
I have read the desired Ca:Mg ratio is between 2:1 and 4:1. So, dolomite has more Mg than is desirable. I mix a little calcitic lime (a 10:1 ratio) to my dolomite to get in the 2:1 to 3:1 range.
* You use epsom to treat an Mg def. About 1/2 tsp/gal of water. (I wouldn't amend it into soil.).
* To treat a calcium def, use Gypsum. It contains 23% Ca and 19% S (by weight). 1g in 1gal produces 61ppm Ca, 49ppm S.
I use dissolved eggshell (calcium acetate) instead of gypsum when I need to treat both Ca and Mg def. Epsom and gypsum have sulfur which, combined, might be excessive. Calcium acetate contains 23% Ca by weight. It produces 60ppm Ca in 1 gal.
Many people use "calmag" products. It's convenient but not as precise to treat an individual problem. I don't like how it (the calcium nitrate) acidifies my nutrient mix. I don't need the nitrogen it produces. So, I go for the individual stuff above.

I dont ph my water, and i use tap, also i use 18 gallons bins, i think im ok. 2 weeks and 2 days in flower and i have almost perfect foliage, it works for me always why fix something that isn't broken? Also before starting flower i always flush with 3x amount of soil, i stick with what it works for me. But tnx for the advice m8. Have a look. Edit: Forgot to say i use no nutrients soil. Npk 0%

Epsom salt supplies mg and sulfur, dolomite lime helps buffer acidic soil and stabilize ph. Edit: Didn't see that az2000 explained in detail
