lol, it will all be a lost cause but if you feel like wasting you time. Flush with the bucket method, ( get a 5 gallon bucket filled with PH corrected water, submerge the entire pot into the bucket, until bubbles stop comming up, drain into another bucket, the more yellow, brownish color to the water that drains out the worse shape your in, do this until the water draining out is clear.) After you do this, let her recover for most likely about a week. Check you PH level. Post a photo up, then I'll tell you where to go from there. The biggest problem is that you got to happy with the nutes and now the soil is toxic with them and your plant cannot absorb any of them because shes locked up. That and not enough light. Like I said before, you'll still be very disappointed in the 'yield' more than likely it will be about 2 dimes worth dried and cured if that. But if nothing else you learned from you experience. By the way, any plant stressed and mistreated if it doesn't go herm will be around that size.
