Hello!

I have two baby cherimoyas that I planted from a seed, one which is now about 6" high and just a stick and the other is about 8" high and has some serious leaf issues. In the pictures it doesn't look that bad, but I know something is wrong.

Many leaves dropped and some grew back. Prior to dropping they had burnt edges. The other, which I took a picture of, has this oddly inward curling of the leaves. Several of these leaves dropped too with the same burnt edges. There are two toward the base that are burnt but still attached. Considering that cherimoyas are suppose to grow quickly, something is wrong as these are stunted. I want to say they are about a year old? They stopped growing a while ago and I don't even know if the smaller one is going to survive. Since then I have brought both of the plants in and they are next to the window sill (but don't get a lot of light because I have a balcony).

I live in SoCal and have been reading about some high salt concentrations in the tap water. My dward Lil Cado Avocado plant has burning at the leaf edges and I saw many suggestions toward salt content, esp since I live in LA. I have transplanted the chermioyas into larger pots with potting soil and a lot of perlite (I noticed that the roots were not extensive and I keep reading that they have a long taproot). They have been fertilized too.

If anyone can help me at all I would really appreciate it! I want to save these plants!!!
