I water it once weekly when the soil is dry and place it beside a north facing window... it receives bright indirect light from 2/3pm till sunset.
Unfortunately, this looks to be algal leaf spot. Watering on schedule will not be appropriate. These will prefer to remain on the dry side, and down to a depth of about halfway the container.
A moisture meter may be needed to keep track of watering.
Fungicide treatment will be necessary, as well.

My rubber plant has grown 5 leaves. With another coming too. Is it ok to transplant now or wait until it stops growing new leaves
These trees' size will be dictated by the container that they live in. If you want it to remain manageable, keep it in a smaller container. If you are comfortable with it growing larger, then pot it up into a slightly larger container. (This should be about an inch or 2 larger on each side for each repotting.)
They can remain in the same container for years, no matter the size, so when you want to pot it up will be up to you, as long as the roots fill out the container that it is in, now.

Hello! I bought a rubber tree plant about 3 weeks ago. It’s still in its original pot and soil. I have since watered it twice, trying to keep an eye on only watering when the first top 1.5inch is dry. It sits in indirect sunlight 90% of the time towards an East facing window. Some direct light does end up hitting it every couple hours some days, but only some leaves. I rotate it often. I’ve noticed these brown crusty tips with holes in them. Any ideas?? It’s only on about 3 leaves. Also this small leaf at the very bottom fell recently. Thanks o much in advance!
These trees are very drought tolerant, and not tolerant of wet soils. Any spotting will likely be due to overwatering. The container needs to be allowed to dry out very thoroughly, and can even dry out, fully, to the bottom.
I would recommend treating with a fungicide and only water once the container is almost fully dry down to the bottom. This tree will prefer neglect over too much care, though some sources recommend keeping the soil moist. I wouldn't recommend this, since they are prone to infections.

This plant is growing on my large palm tree. What is it? Should I keep it or rip it out? Thank you.
This is quite interesting. Somehow, there appears to be a rubber tree (Ficus elastica) attached to your palm! Trees don't usually graft outside of their own species, but in some rare cases it can happen. There are two likely scenarios here.
1. The tree has grafted to the other species, or
2. A rubber tree seedling has sprouted in one of the old leaf stem areas.
I think that you should contact your local extension service and show them, or see if you can get up there and check to see if it is attached, or just rooted into the tree like a pot.

Hi, I have an Indian Rubber Fig plant of the Ruby/Tricolour variety and have had it for about 6 weeks. It seems relatively healthy and has recently produced a new leaf. However at the bottom of the stem there are some veiny brown lines that are growing upwards and two of the bottom most leaves have a dark brown dry patch on the edge. Is this a sign of infection or over/under watering? Thanks
Most often, brown edges indicate too little water. Here is care information that should help:

According to your article on how to propagate a rubber plant, the leaves shouldn’t touch the sides of the glass or clear plastic covering. Can you tell me why that is? Will it not work if they do? I don’t have a large enough covering for my rubber tree cutting to cover without them touching!
It's best to avoid touching the sides because, if they do, mold could develop between the leaf and the plastic or glass. It will still work if they touch.
It says in the article you can cut the leaves in half so they don't touch. Or, if you are using a plastic bag, you can blow into it to inflate it to keep the leaves off the sides as much as possible. Then use a twist tie to close the opening and keep the air inside.
The stalks of my rubber tree have turned to bark fairly quickly. Each of my five stalks grew 3-4 leaves this year, and yet the bark growth has significantly out paced them, leaving only 2-3 leaves on each stalks. (As the bark creeps up, the leaves on the bark drop) it seems otherwise healthy other than *mildly* curled/droopy leaves.
You may be overwatering. Also check for insects such as scale (which could look like bark). These articles should help pinpoint the problem.
