Sunburn, over watering or nutrient deficiency? (2 new leaves tho!)

First, check out the two new leaves! Well 1 new leaf and one in the beginning stages. But the rest of my leaves are starting to get a yellow edge. I read it could be sunburn, overwatering/root rot or nutrient deficiency. Someone once told me I had this plant in too big of a pot but there’s so many roots I thought this pot was right.

I can downsize the pot and the soil I used was Miracle Gro 🫣 I know I knowww I just used what was available at the time.

Any insight or advice is welcomed. I want this baby to thrive 🌞

It’s been about 2 weeks since I watered her. I put her out in the rain and then bam, had 2 new sprouts.
