What do you think is wrong
You should be providing as much information as possible about environment - soil, water, PH, lighting, humidity, strain, temps, light cycle, age, seed or clone.. I mean if you want real help growers would need to know all this and more.
If you are looking for opinions, its doesn't look like this plant can make it to flower and finish, but these are usually really strong plants.. you never know, if you are able to correct all the issues you could *maybe* save it.. may not be worth the effort though.
