Just checked my pH levels : 7.0-7.5
I see green veining in the yellowing leaves. Could this be some kind of nutrient deficiency?
Hi Ali, I think it’s definitely your tap water. So knowing your Ph you can now mix vinegar into your water to get a Ph of around 5 to 5.5 (rain is 5.7). Add small amounts of vinegar until you reach the desired Ph. Each time you add you will have to stir and then let it stand for a while to get an accurate reading. I personally think this is where your problem lies. Give it a couple of weeks using this vinegar water and you should see a huge difference. You may however have lost the defoliated branches but Azaleas grow pretty well so you can replace fairly quickly.I would also check your fertiliser to see if it contains chelated iron. Keep us updated with lots of progress phots.
