Plant wont grow

This thread is doesn't give much info, so if no one can help me its fine,
it has been 5-7 weeks i threw some seeds out in the backyard to see if they would grow. I have no idea what the seeds are, and I haven't been doing ANYTHING to them. Honestly I'm kind of amazed how far its grown. But its been five weeks and it only has 7 leaves, the top two are beginning to become large. Is this right? cause i've seen a whole bunch of pics of 5 week plants and they are pretty big. Most of them were indoors though, and they didn't say if they were clones or not either.
So i was wondering, is this what is supposed to be happening considering I haven't done anything for the plant and if you think its going to die, what should i do to help it survive? since it's already started growing, i feel obliged to help it survive.

They grow at their own pace. How much direct sun do they get?

well if you have been researching indoor grows then thats not the info you are looking for.... remember when it comes to indoor grows people are using artificial lights so they have better control... the outdoors is so unpredictible. it could be full sun for a week then rain for 2... so if you expect your plant to survive at all you will need to take more care of it. if you dont feel like doing too much then do this...

go to your local garden shop/home depot/lowes/walmart and buy some tomato plant food - use that for the vegative growth only water your plant(depending on solidity of the soil) only water your plant once every 3 - 4 days, to check and see if it needs water stick your finger 2 inches into the soil next to your plant, if it feels dry then water it. also when feeding your plants, at first, only use a quarter-half strength dose of what the plant food directions say or else you will burn the plants. as that food is designed more for veggie gardens than mj but it will still work. and remember when feeding that you only add the plant food to your water every 7-14 days.

once the days get shorter and you notice your plant beginning to pre-flower(if its a female) get yourself some bloom nutrients. and do the same as i said above. buy harvest time you should have some decent bagseed bud to burn! and between the two plant foods you might spend at most $20 hahaha it would cost you more than that for a bag!

its a weed man. just like you threw seeds and it came up, water it and you will either get some nice buds or a male. I would say just love it. dont over water it

and i would say to go get some fertilizer... y can love it all u want but if u dont feed it ur gonna have a bunch of popcorn nugs that arent even worth trimming...

Whats the soil like? Compact black dirt? Dig her up leaving the roots in the dirt chunk and put her in a large hole with at least potting soil in it. Make sure to water after done Water, Light, Soil.

My plant is in pretty well fertilized soil its no ocean forest, but its etter than miracle grow. ill put up some pcs later, i dont really want to spend any money. On this plant cause im saving up for my indoor grow, i just found this in the backyard and was just wondering if i could salvage anything from it. Do you think guys think that i could just use 1/10 pee and 9/10 water solution to fertilize t? I have a pretty good diet, and im going to start taking those multivitamins.

It gets a decent amount of sun, i live in ga, and its june so its hot as cod black ops outside, and i think i got sunburn for staying outside for like 3 hrs
