NN,
You really need to provide more info for the best response. K+ deficiency occurs most commonly when a nutrient lockout occurs from overfeeding. You also could have a Mg issue going on. Can't really see any yellowing between veins but crispness/burning at the edge can be related to Mg def.

Raise the light if it's less than 22" over the plants.

Thanks for your reply, my bud
thabks for your guys reply, I believe it’s 4 weeks into flowering and I will raise my light because it’s around 18” right now. At first it was the bottom leaves that started dying off. They would turn yellow and brown and shrivel up, I thought that was normal since they are flowering but then I notice these brown spots the other day and they are progressing kind of fast. I haven’t given her any bites lately and I’ve been watering with a PH of 6.7

I'd say a light and K def combo. You've got some praying going on, not bad, but some. The burns are most likely K def from your ph being just a tad higher. If you can back that down to 6.2 or so and give just a bit more K, I think you'll be fine.
