As someone has suggested, this is more likely to be ammonia or something else. Oxygen shortage is next to impossible in planted tanks unless they are overstocked, and this one does not seem to be anywhere close to that from what one can see in the photos.
Check ammonia, nitrite and nitrate. And pH, tap water and tank (shake the tap water for several seconds to degass the CO2 before testing pH). Any sudden major change in pH can do this. Beyond that, I assume you did use sufficient de-chloorinator (water conditioner) when you filled the tank?
