What is going on and how do I fix it?!
I was in the hospital and out of my office for 3 days! It looked pretty good when I left πŸ€·πŸ»β€β™€οΈπŸ€·πŸ»β€β™€οΈπŸ€·πŸ»β€β™€οΈ

Oooh that looks like spider mites ☹️. Recommend trimming off the yellow leaves, hosing his foliage down with water to knock off the spider mites and the webs, then spray both sides of the leaves with an insecticide (there are good natural ones) and wiping the leaves down after. Then we wait and keep an eye on him. Good luck!
@thorny4plants is that why the leaves are dying? My mom thinks it’s scale insects
So both spider mites and scale do cripple the plant in order to gain nutrients. I mainly say spider mites cause they’re known for their little webs that are on the stalks and leaves…which that looks like. And spider mites are a common pest specifically for dieffenbachia.
I just had this problem with my little alocasia! It’s mealy bugs, if I am seeing correctly. Either way, for mites and mealies the treatment is the same. Give a spritz/wipe down with some peroxide (that will kill the existing bugs), and then treat with a neem oil soak. Neem oil soak: mix some mild soap/castile soap into water, add several drops of neem, and then douse your plant’s pot, especially the top of the soil. Let the plant absorb the dilute mixture, because any bugs that try to eat the plant or that are in the soil will not then survive. Treatment lasts ~22 days. If you don’t have neem on hand, you can also use diatomaceous earth on top of the soil to do away with eggs. Hope this helps!!
@emmybee thank you! Could this also be why the tips were looking dried up? Or is that another issue
@Cassie_opeia86 Definitely could be!
