Ok, maybe I am missing something...small grow area, small amount of cfl lighting, and 20...Twenty...TWO ZERO seedlings? You have serious issues already, improper ph, a mystery and improperly mixed medium...Etc I will stop there because I do not want to come off as insulting...I want to try to help you out here. I don't normally give other advice than reading and studying some more. I don't mean all night cramming I mean real study.
First ..CALM DOWN! Cultivation is a wonderful hobby and it is very exciting to start out, been there done that. For a couple of months I studied and studied, I had not even bought a seed before I had everything I learned I needed to start. I learned a lot about nutrients, feeding, watering, lighting, ventilation and a million other things on RIU alone.
Just by taking some time to stop and REALLY learn...as my signature states you can cultivate cannabis and avoid growing some weed.
Growers HAVE been successful on very low budget so I am NOT telling you to sell your sister for some grow equip...LOL!!
Big $ is not totally necessary to have a decent grow.
YOU CAN DO THIS!...Why am I so sure? The first plant I ever grew weighed well over an ounce and is the plant in my avatar pic.
Good Luck and Great Growz
