Growing Jacarandas from Seeds (indoors)

I’m looking for some feedback on how the jacarandas I have germinated from seeds look. They first sprouted about 5 weeks ago. I’m using two barrina T5’s to supplement the light from the east facing window to keep them from getting too “leggy.” This is my first time growing a plant from a seed and I made my own potting mix.

Do they look healthy to you? I think they look great but I have no references for how they should look at this stage. I’d also like to hear from anyone else that has grown jacarandas from seeds indoor. Thanks!
