If you post some pictures then that might get you better info. I am still new myself but will try to help with info I have read on here. I have only done the indo thing so far. Reg lights won't give you the light you need. Also the plants need a lighting sceduele. Also you need to pick one indoor or outdoors. I really think its a bad time to try to grow outdoors. I have read to start outdoors after the last frost. Like you I live in warm weather.I'm not sure if that changes. But I think it also has to do with the kinda light we get. as to what time of year it is.

If you have a place to put them indoor and can put them on a 24hr light sceduale that would be good. The thing is you would have to at least get some CFL's to give them the light they need.

It would be better if you can get them in thier own pots. You didn't say how old they are so not sure you can still do that. You will need another plan like getting a bigger pot like you can transplant them to.

As for the burning with the ferts you need to flush them with water that has the right ph. You really need to keep the ph at 6.8 or close to that.

If you really don't want to deal with any of that then just plant them in the ground flush them with water and water. It sounds to me like that would be the best thing for you if you don't care one way or the other. That way you give them a fighting chance and if they die it won't really matter.

Growing is just like anything your going to get out of it what you put into it. If you don't care what the weed taste like or you don't care about yeilds just stick them in the ground and check them every week or so till you want to harvest.
