EDIT: I have realized the white fuzz was mealy bugs and wiped them off with a cotton swab and alcohol. I'm guessing they may be the cause of my plants 'scars'?
I have had this jade plant for 2 years. It has recently been developing these brown striations, they look like little scars, but it has been sitting on my windowsill and hasn't been in any sort of traumatic situation. Can someone tell me what this is and if it's normal? When I look it up online the best answer I find is that I'm overwatering but I'm not sure if that's true. I also noticed these white fuzzy growths at the base of some of the leaves. I usually have just wiped it off, but am now wondering if it's also a problem I need to tend to. Please help! I keep this jade in a South facing kitchen window.
