Try the growing sections. They may be more useful to you.

As for feeding, I assume it's still vegging...? If so, you want something high in N (N-P-K). Example/ 5-1-1

If your lady is flowering, you want something high in P (N-P-K). Example/10-15-10

For brands, you can choose any brand you want, except Miracle Grow. You can use it, but it is not made for resin producing plants, so it will be half assed quality.

Organic or chemical? Eiother way is good, but organics tend to be pricey, but is more safe as burning the plant is less of a chance.

Chems. are most common and spit out just as good quality as organics. Just be careful as chem. ferts are slower acting, and a lot of people tend to get impatient, and end up burning the plant.

Hope this helps.

Peace.
