I think you are probably good to flower it, the worst that can happen is you only yeild an 8th. and after all, it's a learning exerience. do whatever you want, if you think drain-o will make it grow better, pour some on there and see what happens. Im not saying you are dumb enough to pour draino on your plant, merely demonstrating that it is YOUR plant and whatever you do, you will know whether or not it was the right thing.
and for the record, i did not call your plant UGLY (nor am i a meanie) I have just never seen one so short with such arge leaves. it's like a baby with full grown hands!!
