Hi, one of my two avocado plants is looking poorly. Pictures attached. I live in Los Angeles, the plants are next to each other, and have been in pots in my backyard since early July. They were both doing well until this week when my Haas took a turn for the worse. It could be an impact of the awful heat we had 2 weeks ago...but my other plants are all doing well. I have Neem oil on hand, but haven't used any yet. There have been some spider webs on this plant. The plants are well watered. I've attached two photos of the unhealthy plant, and one of the healthy plant for comparison. Any suggestions please! Thank you very much. jim
This looks a lot like spider mite damage. This will, almost always, lead to infections, as well.

I'm also going to give you a link to the UC article about this problem: http://mgorange.ucanr.edu/Edible_Plants/?uid=31&ds=530
I started this from a Haas avocado seed. Once rooting took hold I transferred to soil in a 6" diameter pot. Now the plant is nearing 12" tall but the trunk is rather spindly looking. It has plenty of healthy leaves but need to know when to transplant to a larger pot then into the ground and the best soil to use. Also, do I need to be concerned about this being a self-propagating plant?
Be sure your pot is only a couple inches larger than its existing pot. If this is an indoor plant you can repot it at any time, but to transfer it to the ground, wait until spring or early summer when it's warmed up outside. You may want to take a look at your root ball once you've removed it from its current pot; you can trim any dead roots at this time, and gently untangle roots if needed.

Have read instructions to cut stem above fruit. Will something detrimental happen if we pull it off instead? Does this apply to all fruit in general?
As long as the fruit is close to ripe, it should not give you much trouble pulling them off. If they are not quite ripe and you want them to ripen off of the tree, then cutting them with CLEAN shears will prevent extraneous tearing of the bark. Tearing too much of the stem can introduce infection, as can dirty shears!
I prefer the twist and pull method, for the most part. As long as you are careful, it is very safe to do so.
This collection of articles will give you more information on avocados:
I planted an avocado seed outdoors and after many years the tree is huge and just the other day I found one avocado, but it never flowered like I’ve read. Can someone explain why after all these years I only have one avocado and is way up high. Should I somehow remove the avocado? Why only one? Thank you
Unfortunately, it can take up to 13 years to see a decent fruit set from seed. It could also be that there is not another tree of the opposite flowering type in close enough proximity to promote fruiting. They will not fruit very well on their own.
As for the fruit that is on there- It won't make much of a difference whether you leave it on or take it off. Either way will not harm the tree in any way.
Here is an article for more information:

We have a bacon avocado tree and a lamb Hass avocado tree. Usually the lamb Hass avocados are ripe by now but this year still not ripe. We had the tree pruned this summer and that may have affected it. Trying find good resource for avocado trees
Your university extension has some good resource fact sheets on avocados. Lamb Haas usually are harvested from May to August. Only light pruning is needed for shape or to maintain size. Remove damaged or diseased limbs at any time. Also remove any suckers that grow below the graft.
This publication tells how to determine ripeness:

8 year old tree, Little Cabo variety, very healthy and lush. Produces male flowers for 5 days then female flowers for 5 days. No other trees in the area. I can plant a tree next to it, but what kind?
The info in these articles should help:
