Hi guys,

Got a lemon citrus tree showing signs of discoloration on leaves and some of them going brown and crumbling on the ends. I've watered it recently hence why the soil looks wet but have inspected the roots and no visible signs of rot. No visible signs of bugs or pests that I can see and I am fertilising is scarcely one a week with liquid fertiliser in the water. I'm spraying the leaves every other day with an atomiser. Any advice welcome!

cut the fertiliser too much. Not enough light or humidity. It should ideally be in a greenhouse where the conditions are better. Stop spraying the leaves not doing any good. During the winter the temperature should be just above freezing.
