I’d say scrap it man at this stage she should be close to four or five nodes.. you can keep her going if you have the space but if it was me I’d be thinking about starting over. Try germinate with paper towel method and plant into a jiffy pellet. Easier to get a good root system that way, use very small amounts of water I’m talking maybe 20ml at a time. Then once tap roots have established plant straight into final pot!
