Start over. Already told you.
Your plant has undergone wrong lighting, worng soil, you got like a 5 gallon pot full of seed starter soil. Go buy some organic soil, check the nute levels on the package, start you seedling in a smaller cup and do this thing called "transplanting", I'm sure you can google it.

Get rid of you current plant, just let it go, it is not going to make and this abuse set it back quit a bit. Not worth the time and effort.

Do some research, apparently you grew outside in the past, after reading your old posts it seems like you should have some common knowledge with horticulture. Do some research, we are not here to hold your hand and teach you ropes, you get out of it what you put in.
