Pilgrim's first grow

My first grow, I have two plants but only posting pics of the big one. The other one is still only like an inch high but sprouted a week earlier than the one with pics. (each pic is about a week apart) about 3 weeks in now and it's like 13 inches can anyone tell if it's more sativa or indica or what? they're bag seeds I don't know and tips would be helpful. Thanks.

 

I'm just eyeballing the whole thing dude. The light is a 120watt flouro. the soul is organic and i had bat guano in from the start. I am not monitoring temps. Light's about 14 inches off the top leaf. The pic actually isn't stretched, I was wondering myself why the stalk is so long with not much veg but that's just the way it's been growing?

 

that's how i cut it after it snapped trying lst. it was too tall and hard already. anyway can i make what's left root? or should i just get more seeds and try again?

 

thanks a bunch.
