Kalanchoe beharensis 'fang'

Are the rough edges of the bigger leaves a sign of poor watering? Does anybody know if there is anything I can do about it? :\

I think you’ve got Kalanchoe millotii, but it doesn’t matter much because you treat ‘Fang’ and millotii the same way. What do you mean by the rough edges of the bigger leaves? If anything your plant needs stronger light, but acclimate slowly.

Kara is most like correct - K. beharensis 'Fang' has much bigger leaves, and underside of them are full of "protuberances". It also grow quite tall, even in pots and more so in ground. There is also K. beharensis without "protuberances"; but leaves are also much bigger and less hairy than 'Fang'. Here are leaves of 'Fang':

What I meant by the rough edges is that there is some browning on the tips (it kind of looks like the edges are drying out) and some leaves appear to have scars on them.

As for the lighting, I recently (about a month ago) put them in a space that has more sunlight, so I am hoping that that helps.

The little brown marks can be from something that took a bite (some type of insect) or it can be from physical injury. It's very minor and nothing to worry about. Enjoy it! Someday it will have flowers.

Thank you all!! One last question: how often should I be watering it?

I’ve been watering it twice a month during the winter months (I live in Canada) and I was told once a month during the summer. I was wondering if this was the right way to go about it or if I should be doing it more often. Thanks in advance:)

I water all my kalanchoes (do not have same as yours, but have others) more often than what you mentioned. Perhaps 1x every 3-5 days? Recently, they got rained on 2x in past few days. I am also in Canada...BUT it depends if they are in well draining mix - and how warm they are during the winter. Here is above-mentioned 'Fang' - this morning, just after it rained:
