Avocado leaves turning brown

Avocado    Pakistan

My avocado leaves are turning brown on the edges, I have sprayed a very dilute broad spectrum fungicide/miticide and tried to flush any salts as well. Its planted in well drained coco-peat and has very low quantity of fertilizer at the base. Appreciate your help

You can use coir just like peat moss. It often comes pressed into bricks, which have to be soaked to break them apart. The product is also found ground into dust, which is called coir dust, and is used to grow many exotic plants such as ferns, bromeliads, anthurium, and orchids.

I don't think you have a fungus infection.
The symptoms are more characteristic of nutrition deficiency (Phosphorus or Potassium).

Hi, thanks a lot for your answer. I've read that avocado plants are notoriously bad with fertilizer.....are you sure it needs more fertilizer?
