Something wrong with my plant.. Help please?

I left it outside today and some of the leaves had been scorched or something.. I immediately felt the pot and it was pretty hot but I'm not sure why the top of the plant was slouching over. I watered the plant immediately as well and the top started to stand strong again. These are some pictures with the leaves. Some have a yellowish discoloration because days ago I put fertilizer and i didn't know what I was doing so please don't flame me for being such a noob. After I realized what the ferts were doing to the plant I transplanted it with the same soil as before without any ferts. I was stupid when I did that so yeah. Please help me out it's my second time growing and I really think my baby is a female..

Looks like fert. burn, i dont know what you are using and how much you gave it. I also dont know how long you have been giving it fert. but good rule of thumb is start like 1/4-1/2 strength and slowly increase it otherwise you will fry the roots and in turn the leaves/or plant will die. read the bottle and go off that.

thanks a lot Jamaican Mon' ! i've really needed help for a while and nobody has really offered me any!
