Hi folks!

I assume this should be a tabasco pepper plant (got it from one of my relatives last autumn, it has been overwintered), and the fresh leaf growth are turning yellow recently. Although i started to move the plant outdoors for the daytime several weeks ago, i wouldn't think it's caused by direct sunlight.
Could it possibly be calcium deficiency? (I fertilized it like two weeks ago applying ordinary fertilizer)

In addition, i also caught sight of lots of really tiny white dots on some of the leaves causing them turning brown, and the affected leaves come off easily. What could it be?

I hope i can post another picture as well demonstrating the former. (I'm new to this forum)

Thank you for advance!
