    Default Is this a bacterial infection?

    This past Wednesday I purchased this Monnierara Millennium Magic 'Witchcraft'. Today I noticed that there are faint brown spots surrounded by translucent rings on most of the leaves.

    I'm concerned that his might be some sort of bacterial infection. Any thoughts?

    Seem like bleached either a sun burn or a spill of some sort. I could be wrong

    I speculate that the center of each spot is the place where an insect has bitten the leaf to extract the juices, leaving an infection entry point....

    Unless they continue to grow or spread, I think the damage is done.

    I agree. However those damaged cells are possible points for bacterial or fungal infections to attack the plant, which might be countered by occasional light spraying with a plant disinfectant, e. G. Physan at perhaps 1:2000 dilution.

    Thanks for the feedback everyone. I'll keep a close eye on it over the next few days.
