hey! should i remove these leaves with spots on my umbrella tree? i can’t tell if they’re sunburnt or if it’s the result of a bug. it’s just the lower leaves as of now but i’ve noticed a couple spots higher up that were not there before. it’s got regular watering and south facing window. about 3 feet away from the window. as a result the top leaves definitely tend to get more light but as the lights moves, i’ll pull the pot further away so the lower leaves can get some as well.
