Holy luxuriant

I’m sick about this I’ve had this since June 8th. So I think it could just be from lower humidity. ( need to get a cabinet for it) it was from ecuagenera. Just getting these holes and cracks along the veins of the leaves no root or stem damage at all I even see new growth on roots and growth points. It was really close to a window for about a month so im thinking it’s either humidity + sunburnt or both. Is there any way to stop the holes from getting bigger or to prevent this in future?
