I have a couple 3 year old seedling Melicoccus bijugatus (I call it them mamones, aka spanish lime or quenepa). The plants are very sensitive to fertilizer/salts and dry soil. Even a very dilute application of FP (8x dilute from normal dose) causes the leaves to drop. This isn't a disease per se but I though maybe you guys could help diagnose a general lack of vitality in one of the plants.
It seems to lose leaves at about the rate that it grows new ones. The leaves come out looking perfectly normal then over the course of a month or so will develop these small crusty looking spots that do not wipe off. The leaf will begin to yellow (light spots are starting to develop in the photo) them dry up and drop off. Here is photo with the crusty spots and the beginning of the discoloration... Thoughts anyone?
It occurred to me that the plant may be sensitive to chlorine so about 2 months ago I started letting the water sit out overnight to dissipate the chlorine. So far using evaporated water may be helping, but it is too soon to tell. I also found out we use chloramine in our water here and that overnight isn't sufficient to remove the majority of the chloramine, so I'll be switching to filtered water.
