The leaves start to turn brown usually from the tips, on one of the plants it starts all over. BUT always with the older leaves.
New leaves continue to grow but... they are starting to look kind of ugly.
What am I doing wrong?
These tree's were grown from seed and they are not even a year old. I would like to have atleast one good looking avacado tree. None of my other plants have this problem.
They are not fertilzed and I am pretty carefull about giving too much and too little water as I have read that may affect the plants as well, their watering schedual is fairly regular, every 4-5 days as the soil drys out.
