(And also to @MrPeat)
I thought it could be light burn but in my other post looking for help with this problem I was told the light is underpowered and recommended I buy more powerful lights. You can understand how being told I had underpowered lights on here lead me to believe there was no way it could be light burn. You can also see in that linked thread how high my light is from the plant (pretty high up, IMO). The plant exhibited these issues both with the light on only veg switch and with veg + flower switches both on.
