That plant is looking like it needs to be killed and to start over. Its has undergone enough stress for a life time. I would suggest growing in a tent or something were you can control the light that hits the plant. If you can read words on a page from a book that means there is enough light for the cannabis plant to have its dark cycle interrupted. The long single prawn leaves are suggesting the plant is entering veg and flower and back to veg. I don't fully know if this is the case from light leaks or if the plant is just a mutant and needs to culled. Some of the leaves look warped and that can also happen from overwatering as the roots rots from being to wet. All this maybe in part from where the seeds came from you are growing, I think you would do much better by starting over and using some good quality genetics from a known breeder. There are tons of seed banks and options out there. Good Luck!
