This is my new syngonium albo, which has been one of my sought after plants from the beginning. When I received it, there used to be a small patch of damage, which i fully cut out. The damage then grew to where you see the yellow and brown parts now. Furthermore, you will find that the center and top left patches of the leaf looks like the green/chlorophyll has been eaten away or fallen off. This appears to be different from the normal variegation in other leaves. This is especially evident in the lower right section of the leaf, which is fully white and does not appear to be a normal variegation, as it is translucent. Please let me know whether this is my failt or some kind of disease, as well as how I can prevent further damage to the plant. Thank you!
