Philodendron losing colour

Please help! My philodendron is slowly losing the green from its leaves (see photo). I’ve treated it for a fungal infection but it’s not helped. Can’t see any critters on it anywhere either. Any advice? I’ve never known it so this before. Thanks in advance!

    It's not a plant I know or grow, but that leaf looks like it may have spider mite damage.
    You can't see the bu**ers without magnification though.
    Have a look on the back of the leaf with a magnifier and you may find the two-spot spider mite - they're almost transparent, but you may see them.

  • Thanks Pete! Good call - despite my previous checks I found some tiny black things scuttling around on the underside of several leaves. I’ve given it a good spray with bug killer so hopefully that’ll do the trick!

    Maybe it will, but if they are spider mites, general bug killers will have little or no effect.
    I've heard that neem oil can get rid of them or if there are not too many leaves a soapy wash of the leaves may shift them or some cotton wool with rubbing alcohol/vodka will kill them
