The plant is leaning over. Should I be concerned?

The plant is at an angle going into the soil. The plant cones out of the soil at an angle and curves upwards to the light straightening itself out. It wants to grow up towards the light, so it corrected the angle it had as a seedling. I don't think anything bad should happen because of it. Next time when you plant the seed make sure it's the right way up. Taproot pointed down. So it doesn't have to grow at an angle.

It looks like you trained it that way. If not, go with it. The first part of low stress training is done for you. The main stalk is over to the edge of the pot. You can start training the lower branches to grow out & over into the open area of the pot to make use of the light. If you take a soldering iron or heat a nail with a torch or lighter you can melt holes around the top edge of your pot. The holes make great locations to tie the branches when training. It's a similar affect to using a net but you can move the plant as needed.

Is your light over that direction. The plant could be just reaching for it.

I wouldn’t be concerned about it as to why it’s leaning it’s most likely due to the lighting
