Browning of date palm leaf tip in container
I am staying in India. Three months back I bought a packet of dates from Kuwait. I germinated the seeds and placed them in clay pot of 12 inch size. I have filled the pot with equal parts of sand and normal soil, and added 75 grms of organic fertilizer to each pot. And now the plant is 10 inches in size with two leaves each. Now the problem is the tip of leaves are dark brown and pointed like a needle. I have placed the pot in sunlight outdoors. I don't know the variety the dates belong to, but their roots grow at a fast rate. Please help me regarding this.
It could be anything from a watering issue to low humidity or even root restriction. Here is an article that you may find helpful: https://www.gardeningknowhow.com/plant-problems/environmental/what-causes-brown-edges-on-leaves-of-plant.htm
