Here are the leaf close ups. Some are just beginning to yellow, others look like they're about to fall off. They do not really brown, only yellow and then drop.

I can't see any sign of pests, I would be inclined to leave them alone for now. Trees do lose leaves when they are stressed, as well as part of the natural growing process. I pick off 3 or 4 yellowing leaves daily from my Fukien Tea right now, it's fine. I have reservations about grow lamps, I don't use one but my understanding is that to be effective they have to be really close to the plant, ie within a few inches, which risks local heating & drying out of the growth which is nearest. May depend on the actual type of light source and it's probably worth you researching this further.

i do not know much, but i can see little black dots on quite a few of the leaves, like a fungus, may be wrong.

The grow lamp directions said to keep it at least 10 inches from the plant. I was afraid it was getting too hot so I moved it up a bit. I will measure out 10 inches and then keep the light there. Hopefully, since I stopped moving my tree, it will adjust okay.

I'm inclined to believe that your Ficus is trying to adjust to the changes you made. Scale is another pest that could be causing the leaves to yellow, but they are easy to detect and you would notice the sap-like "honeydew" they secrete on the leaves. I had a Ficus for 15+ years and had the same problem with the leaves yellowing and then finally dropping as a result of to many changes. The poor tree was stressed. Again, they are pretty finicky. Keep a close eye on it, and be careful not to overwater. My tree finally did rebound and continued to grow well for another 5 years, but unfortunately it finally did succumb to a bad case of scale and I lost it, sorry to say. Rudy

I was looking over my tree today and I saw a spider on it. I have seen spider mites before and I do not think it is one, but I am no expert, so I took this picture of it before I killed it.

My tree also gets these little bumps on the branches from time to time. Here is a picture.

The leaves keep yellowing, I am afraid that in a few days it will have no leaves left :c Will my tree die if it does not have a lot of leaves, or will they grow back?

The pesticide that I purchased when I had a problem with a different plant earlier this year says that it will treat mites (including spider mites) as well as scales, so if any of these are a reason for concern, I do have spray available.

I am certain that the "little bumps" you mentioned (photo 1)? are?scale and?is what's?causing your leaves to yellow and drop. ? It?can actually kill a tree pretty quickly,?depending on the infestation, and if left untreated. ??The best way to get rid of them is a systemic insecticide. ? Scale attach themselves to the branches and leaves and suck?to feed. ? They?are very?difficult to manage when they reach the stage that you are seeing them?now. ? A spray will only kill the "crawlers" ?from the?newely hatched eggs. ?The lifecycle is almost imposible to break with a spray insecticide only. ?A systemic travels throught the plants complete?system - from the roots to the tips of the leaves. ? Try and get an organic brand if you can, the others? are pretty harsh on the environment. ??The spider you killed was not a spider mite. ?In fact, it's good to leave them on your tree if you can controll them. ?They actualy help protect against many of the pests that attack trees and plants. ? It's part of natures way of?helping to?keep things balanced. Here's a couple?links about?scale, I hope this?helps. ? Good luck. ? Rudy

Thank you so much for linking those to me! My plant has had symptoms of scales since I got it and I didn't even know ;( Hopefully now I can save it!

I read over the links and individually cleaned each leaf of all scales and black fungus stuff using a cotton swab with alcohol, as the links reccomend. It lost a lot of leaves in the process but hopefully it will grow back.

I do have a pestacide spray but I have used it before on this tree earlier in the year for prevention, and it clearly did not work. I am looking for a home recipe I can use, and there are many different onces. And then soon I can go out and look for a systematic treatment to use.

Thank you very much! :)
