What kind of deficiency or stress does this plant possibly have?

Earlier it was kept in complete direct sunlight with too much heat. After that, the older leaves started turning reddish-brown/bronze while the newer leaves stayed greener. Some leaves also have yellowing and slight curling.

The soil is quite compact clay-like soil. Could this be sunburn/heat stress, nutrient deficiency (potassium, magnesium, etc.) or root stress?
