Do over?

Why in heaven's name would you want to get rid of a plant that is growing? You have basically no big problem with her - I would take Roberts' advice and cut any feed in half - if you're not feeding her, just have some patience and she WILL grow out of this! Funky looking leaves are pretty normal in a lot of grows.. you have nothing to worry about! Good luck!

Classic case of overcaring and too much light. As a rule of thumb, I'm with just rooting tonic and water until the fat seed leaves pale and yellow and then a 1/4 strength of nutrients, building by 1/4 a week with a complimentary system like canna. I use Rhizotontic 4ml/ltr. It is saleable and some carry on to live their best life and be most rewarding, I love early days period, but don't overcare!

Reduce light until it starts to stretch out properly... then, as it stats gowing you may need to crank up light as it matures. (40 DLI is about as high as you want to go with ambient co2 and loosely controlled temp/rh in safe ranges) you'd stunted it a bit... it may take a few days to respond. Still probably faster than 3-5 days to germinate and 7-10 more days after sprout to catch up. by that time this one should be showing 4th node and starting to grow like a normal plant tht first pic looks like all the nodes are super tight. this is due to too much light. it may have stunted growth or will eventually.
