Weirdest seedling

Hello, I am a newbie also this is my first post at rollitup. I would like to show you the photos of the weirdest (i assume) seedling, it looks like a bonsai plant. It has been in a pot for 18 days. It is an ak47 auto - bought 3,5 years ago - this is the only one out of 5 that germinated.
- Indoor - however my grow room setup is not ideal, i cannot lower the heat to ideal degrees.
- biobizz all mix
- 400w hps - this might be a problem, just ordered a 100w cfl.
- started with 20/4 cycle, switched to 18/6 day 10.
- I was watering it daily with 50ml osmosis filtered water but 10 days ago i stopped watering daily, now i just focused on keeping the soil moist.

I will definitely not put it under 400w hps again, i am planing to put it outside to under daylight until 100w cfl arrives

I will let it grow, but i am wondering what is this and did anyone had a similar problem?

Soil should be watered then left to dry not kept evenly moist with daily waterings. That seedling is missing a proper wet and dry cycle which should be the only way to run soil.

Thank you for your reply. I will hold my urge to water until it looks dry and then water it.

Id kill it start another, its not of to a good startvanyway and might take a while to get going again.

i am wondering what will happen and also it is not easy to find auto seeds where i live. i guess the outcome will be disappointing

Update photos. It is growing in a weird mutated(?) way. I am not planning to upgrade the pot, i guess it doesn't need a bigger one, but i won't be kill it.

Bonus: I found another batch of very old seeds, one of them germinated successfully to become another weird seedling. I hope it wont fly away with the wings it got.

It is flowering
