Opinion on plant condition

First off this plant popped through the dirt on September 7th. Was on 18/6 for 35 days then 12/12. The temp in the room is 78-80 with lights on and 60-62 at night.the water is 6.5-6.6. Notice most of the stems are purple and a few of the leaves are yellowing on the outside. I’ve read the purpling could be genetics or the fact it cools down so much at night. But overall does this plant look healthy to you? And what do you think I could do to help it out. Thanks!

Or purple is caused from lack of mag
1tsp of epsom salt give you about 250 ppms of mag
Maybe wrap the pots with a towel or something to keep the cold off of it.
