Translucent areas on some leavesโ€”whatโ€™s it mean?

Are these sunburns? I put the plant outside because I didnโ€™t think it was getting enough sunlight indoors (next to an East/North-East facing screened window beside my kitchen sink; oldest top leaves were yellowing). Or is this a sign of overwatering? #Aglaonema #ChineseEvergreen

Looks like oedema. My aroids have oedema for a while when i just bring them home, but they go away after a week or two. But generally oedema is a symptom of overwatering.
@Araceae Thank you.

The translucency continued to spread today (look at first 3 pictures) to the rest of the one leaf in the first picture I initially posted and this one leaf completely drooped. When I touched the tip, it was dry, flimsy, and had browned. However, the base of the leaf was wet and a darker green. Other leaves look the same as they have except one just beside the translucent one that seems to be turning pale/light green (fourth picture).

I last watered a few days ago, and before that (last week Thursday), a chug load of pesticide poured into the soil so I guess youโ€™re right about the overwatering (soilโ€™s still pretty wet).

The weather right now is colder and quite dry (especially in the mornings and nights) so Iโ€™ve moved it farther away from a northwest-facing (screened) window in a room with two windows (other north-east one doesnโ€™t get much sun or air) and Iโ€™ve poked holes in the soil.

What else can I do?
@SocialRubberfig Just did a comparison and it seems the leaf in the second picture I initially posted is also worsening (yellow hue is spreading).
@SocialRubberfig That is sunburn. Aglaonema loves bright light but not direct sunlight. Try cutting it back and fertilizing it to help it recover. All the best!!
