I've had this split leaf philodendron for around 6 months and I noticed some yellow leafs with brown dots while moving the plant I've been keeping plants for a while now but I've never had anything but scales before. Thanks!

Are those discolored leaves still attached to the plant or have you removed them? I ask because overall the plant looks very healthy and it is not uncommon for some older, lower leaves to gradually die back as the plant ages and adds healthy new leaves on top.
