OK. I think that is fertilizer/salt damage. From personal experience killing 20 or so young mango trees, it does takes months for the damage to show, and the leaf drop and burnt leaf margins are exactly what I experienced. I talked to Dr Richard Campbell about it, and he said that mango trees are super sensitive to ammonia, which is more heavily present in some nitrogen sources than others. He said that the best way to kill a young mango tree is to plant it with a fish, since the fish will eventually rot and release ammonia.My LZ was a bit anemic when I got it, I repotted it in gritty mix and have been splashing it with Foliage Pro fairly regularly. It appears to be making a pretty strong comeback. I have a Cogshall that I'd occassionally dose with Scotts citrus fertilizer, I torched some of the lower leaves bad. The citrus seems to eat it up, I won't use it on mangos anymore. I hunch that the urea based nitrogen is the cause.
Here is a presentation given by Dr. Crane on cold and freeze protection.

Based on the first data slide, it appears that Iona is well protected from cold but there is no indication of how long temperatures have actually been recorded there.
This is kind of off topic, but in Taiwan, there are hot spring spas where they have a pond of guppies that eats the dead skin off your feet when you put them in.
Almost every massage parlor in Bangkok has same: Guppy foot massage. Feels REALLY bizarre.
