Need help with my Rubber Tree Plant
I purchased two young Rubber Tree Plants last month. They came in two 4" growers pots. I put the two of them in an 8" pot. They seem to be doing well. Recently, however, I've noticed a tan/dark spot on about 4 leaves. The spot is thin on the leaf making it so you can see it on the underside of the leaf; you can see through it somewhat.
What is happening to it? Is it maybe getting too much light? Is that a sunburn? I often struggle with knowing the difference between "direct light" and "indirect light" ... my window is really bright and sunny (it faces West, but there's a tall building next to mine and I always think this helps -- I may be wrong)
