I am not sure what it means that my philodendron plant's leaves are gradually getting lighter yellowish blotches in the center of the leaves. It looks perky otherwise and there is a new red leaf still rolled up and ready to unfurl. It is in the middle of the room so it gets no strong light from the north window in the mornings. I check it constantly to make sure it hasn't dried out too much but I water it sparingly. Could it be something else? It's newish so I haven't fertilized it yet. Thanks for your response

I think you may be overwatering your plant.
Philodendron can tolerate drying out a bit between waterings.
If the soil remains moist or soggy the plant can suffer from root rot.
Make sure the pot has an adequate drainage hole for excess moisture to drain from the soil.
Medium to bright light location is best for your plant.
