Looks like it leans toward Sativa alright.
And from the length and curlyness of the pistils, the big girl still has several weeks to go.
Those buds are not as plump as they are going to be.

Good job!
They may be a bit rootbound.
I say that because the chemistry is off.
I see Phosphorus, and Calcium lockout.
That usually means low PH.

But since you used no nutes, it is unlikely that it's getting low PH water.
And the Calcium sign is recent, (It's on the newer leaves), my guess is,
Shoes too small for the feet are hosing the chemistry.

The bottom leaves say that there are active fungus gnat larvae in the root-zone.
Without them, those gals would be larger and healthier.
Lay some dryer sheets on the soil surface and it bollixes hatching, and egg laying.
Breaks their life cycle without poisons or bad smells.
If you start with gnat free soil, the sheets will keep it from getting infested in the first place

Just my 2 cents.
Going to be an excellent harvest for all that.

Aloha,
Weeze
