Understand completely brother.. think we're all like that at the start but in my opinion you can grow fine.. u just need a stronger light and I'd be confident you've got the skill/knowledge to pull some quality weed.. you don't have to break the bank.. if u want a recommendation to keep cost down u will not beat a Spyderfarmer SF1000 in your space on my opinion.. I use a Skyline 400 and a little 100 as well.. great lights but a bit dearer.. there are loads lights out there.. do a bit of research and you may get a bit of AFN discount if it's a vendor that's on here..
As for your other plant.. I'm not sure what happened.. I have to think if it was an auto it would have made some effort to flower long before now.. I have a feeling it ain't gonna do anything for ya and may be a photoperiod plant.. just my opinion.
The best advice I can give u is this..
Get a better light.. doesn't have to cost a zillion bucks but read read read before u buy.. try and check out some grows using the light your interested in.
Get a pack of seeds that your sure are autos.. at beginner grower level I would recommend any Dinafem auto you like the sound of.. they're strong and very forgiving.
The small fabric pots will be fine with a better light and I'm not sure you could do any more than 1 bigger pot in your tent.. 2ft X 2ft is it? But something to think about..
Hope this helps a bit. Good luck.
