My mango leaves having the following condition:
The leaves start off with this grayish bluish blotches which turn into this bright orange. Is this due to some fungal problem? Potentially parasitic algal spots?
Or is it due to the plant sucking nutrients out of the leaf because it is not getting enough from the roots? If this is the most probable cause, should I add fertilizer? This plant is only about 2-3 years old and recently transplanted into a 10 gallon pot. It's about 2 feet tall. So I fear that if I start a fertilization regiment early, I might cause some sort of necrosis.
The soil is very nutrient potting soil with lots of well decomposed bark and yucca. The soil also naturally has some miracle gro mixed into it. So I don't think the soil is by any means poor quality.
