Over fertilized?

[Andras]

Hi,
I think that I over fertilized my plant. I have 2 calamansi (kind of a citrus) trees. I gave them a lot of potash, like the double of the recommended amount. Plus I didn't well mix the potash liquid with water so I think the first one got most of the it. While the second one looks quite fine and healthy the first one is seriously sick. It lost most of the old leaves and in the last 24 hours even the young leaves start to dry out. It's a heat wave here recently and some sources suggest that heat and over fertilizing can combined lead to root problems. The old leaves are lost all over the plant by now. The young leaves are starting to die from the top. Overall many leaves were completely dry, some are withered, some are misshapen or curly. Do you think it's over fertilized? If so, is this what I should do? : https://www.wikihow.com/Revive-an-Overfertilized-Plant

You may have over fertilized with potash/potassium but I don't think so. Potash enables the plant to uptake other needed nutrients such as an assortment of minerals, nitrogen and phosphorous..It helps with photosynthesis. To me, none of the pictures show anything resembling an overdose of potash. It looks to me to be a watering issue, probably watering too often. If you did use too much K just remove the plant from the container and wash away all of the soil and repot with fresh soil.
