Here it is usual to put a grease band around the trunk to prevent insects and larvae crawling up to the fruit buds.

Not sure what the brown spots are on the leaves. That isn't soil though - looks like coco coir. If the avocado seed is only in coco coir, then the roots are struggling to find nutrients, as coco coir isn't used for nutrients.
If it were me, I'd replace it with some proper organic seed raising mix - get one that's soft and fluffy to the touch. If it's chunky ...

Aloe, Gasteria and Haworthia can all get black spot like black spot you find on roses. Black spot is growing on your plant because the conditions are perfect for the disease. If water is allowed to get the foliage wet. If not that then it is probably air circulation. The area is too humid. You need to get a fan in the area where you grow the plant. ...

The first problem is that you need to repot your friends. That pot is far too small. The second issue is that it is not getting enough sunlight. This is causing the plants to reach/stretch out (etiolation). The third issue is that you are dumping water directly on your plants, causing the red/brown. Pour the water around the plants, not on them. When you go ...

The spots are called cystoliths that won't harm the plant. It's a natural process along the cell wall of the leaves, in which almost all Rubber trees obtain. They're not pests or larvae, so there's no need to worry!!

I'm afraid the choice of a glass jar for a growing pot is not going to help this plant very much. Likely there are no drainage holes in the bottom so there is nowhere for excess water to go. But that said, it sounds like you have not overwatered anyway so you might not have hit that issue.
The glass will help in that you can easily see roots. You should see ...

Look like the virus pictures I see. Streaks parallel to the veins.
The other leaves looking good means it is not due to other growing conditions.

According to the Royal Horticultural Society;
'Canna yellow mottle virus (CaYMV) & Canna yellow streak virus (CaYSV) both causes streaks of pale tissue between the leaf veins. These later die, resulting in streaks of dead brown tissue
Bean yellow mosaic virus (BYMV) causes a yellow mottling of the leaves'
I do not see either of the symptoms in your ...

I am guessing you have a watering issue. You say you water it when the top of the soil is dry, but how far down do you let it become dry before you water it. It is a plant that likes to always be moist, but never wet. It is a weird plant in that when it is young it starts growing in the ground, a terrestrial plant, but as it ages it become an epiphytic ...

If the leaves went mushy, then you have a one of two things that happened. One is over-watering. The other is a cold snap. If its a short cold snap the roots will still be alive, but the top will be mushy.
I am guessing its a case of over-watering or poor drainage. I believe you did not no over-water, but gave the plant poor drainage to start. When ...
