Hi

Need help with avocado plant. This is the 3rd one ive planted in the past two years. First died from severe socal summer heat. Second one i was told was over watered. Now this current one’s leaves are browning. I’ve watered it much much less. It should have good drainage and it gets plenty of sun. I tried doing deep watering to remove salts but nothing helps. Is it a lost cause?
