Is it a twin possibly?

Since she is in a big pot, you are most probably experiencing over watering. The issue is that when there is an excess of water in the soil, the roots can't take oxygen (they are literally drowning) and the plants growth rate slows down to a craw until the excess water is gone (usually evaporation). Stop watering the pot, which can take a couple of weeks.

Looks completely normal. Small suggestion: don't spray your leaves. You may not be, but the leaf has some residue on it that could have been from rain or a number of different things. Getting the leaves wet can burn your leaves and also make it harder for her to perspire. If she doesnt sweat, she won't drink. If she doesn't drink, she won't grow etc. Looks like you're in good shape though, keep it up!
