Mango seedlings leaf problems
A few couple of weeks ago I planted some mango seeds, which grew just fine (healthy, fast and sturdy). The ones that grew the faster were two Tommy Atkins's seeds which are the ones appearing in the images. Nowadays, some of the leaves in one of them are kind of "burning", but only in certain parts of them. Several only have one little spot that dries up and make its surroundings of the leaf shrivel, or appeared in the borders, which make the leaf curl up.
In addition, a leaf of the first tree seem (in my opinion ,taking in mind that I planted them at the same time, and the other tree's leaves are more green) to be quite yellow, with some dark veins... (the picture does'nt show the leaf affected) PLEASE help me out
