hello, Can anyone identify what this weird white growth is on this plant and what I should do to remedy it? Also, what is could be causing the leaves the ‘freckle’ in colour? Thank you for your time, I really appreciate it :).
Looks like an infestation of scale and spider mites. Scale Management Guidelines--UC IPM Spider Mites Management Guidelines--UC IPM
This plant looks small enough with few enough leaves that you could hold it upside down in a tub of water and massage off all the offending pests on the leaves, stems and trunk. You'd probably have to do that a few times. I'm not sure what you do about what pests are on the soil.
Soil Pest and Root Rot Treatment Mix one part of additive-free 35% hydrogen peroxide with ten parts water. Water infected plants thoroughly. The soil will bubble as the oxygen is released. For pests, water with the mixture twice a week, allowing the top 2 inches of soil to dry between watering. Root pests should subside within a week.
