My avocado is 3 years old. Except summer time, it is always difficult time for it. Due to cold and windy weather, Avocado is always in-door during these seasons. There is not enough sun light in my place, so during day time I turn on bulb to provide additional light to it. Everything was relatively alright with avocado till recently. A few days ago, the bottom leaves started to turn brown at the middle + I can see yellow pattern on the leaves. The process is very quick (within several days).
From time to time, I was able to see a small worm in the pot, but It seemed like not to be a problem at that time. But now, I not sure.
I water it everyday around 150 ml (room temperature). From my opinion the pot is big enough.
Any help is highly appreciated.
Thank you in advance,
