First grow and I'm scared

So I live in northern California. Close to Sacramento. My plants are almost 4 weeks old (on monday they will be 4 weeks). I used normal potting soil (forgot the brand) and that's it. I'm gonna try and upload pictures but I don't know how to yet (gist signed up). When I planted the seeds I put about 5 seeds in a hole with 6 holes in a little 2 gallon or so pot. Well I wasn't expecting this but just about all the seeds sprouted (one I noticed this morning was new). But the 2 leaves on the bottom that first come up as a seedling, those are pretty much yellow/brown and curled up on every plant. I wasn't too scared about that. Then this morning I noticed all the bottom leaves (not round leaves) were losing the green and slowly turning yellow. The tops of the plants however are a pretty healthy shade of green from my untrained eyes. For the past 3-4 days ive been misting them with water instead of putting water on the soil with the exception of yesterday afternoon and this morning. I plan on watering them later today as I wont be back till Sunday. I don't know what I'm doing with taking care of my plants or on this website. So if someone can hep me to post pics that would be awesome. Oh! Almost forgot, plants are an outdoor grow. Sorry if I worded some of this wrong. And please help! I wanna be able to smoke my first grow. Thanks in advanced, bob

doesnt sound like youve got too much to worry about....lower leaves dont always get enough light so theyll yellow and fall off. if its anything else im sure someone with more experience can tell you but youll have to show pics....

Can you tell me how to post pictures on here please? Haha sorry for being a noob

down in the reply section theres an "insert image" icon, upper left, search thru and find the pics you want

Ok thanks I'll try and put them on right now. Might take a little while so give me a few. But thanks again

Might need some nitrogen, but we need to see pics first...

the last picture is cause it looks like a branch is growing off of a branch. its hard to see since its a shitty cell phone pic, but is it just a deformity or what? i think its kinda cool haha. ps thanks again for the help!!

also, sorry for them being small. ill try and take some more right now but bigger. im new at this haha

Can anyone help me?

pics with cam phone still suk but it doesnt look like youve got a big prob. dont know what your temps are there but id water thoroughly about every 2-3 days. could look into some ferts if your soil has none.

looks like a nitrogen deficiency but the pics are really small and kinda blurry
