Is this deficiency or disease? Any ideas would be appreciated

At first glance, it looks like your plant has been over-fed.

However, before we jump to that conclusion, tell us more about your grow. What kind of lights, the distance to the canopy, your media (soil/coco/hydro) your nutrient/water schedule, the temperature/humidity and so on ... Also, please post full plant pictures so we can see the rest of the plant and how its doing instead of just the damaged leaves.

Looks like physical damage to me. You know, like a cat chewed on it.

That makes sense ... especially if nothing else is damaged.

Its stardawg fast buds auto on week 10 and the medium is basically just peatmoss with gia green nutes at 2 tbsp per gallon I used less then the recommended amount I have added big 6 at 1/2 ounce per gallon and I just noticed all the leafs getting a purple hue and yellowing at the tips also crispy like burnt. Lights a 400 watt Mars hydro about 1 1/2 foot off the plants

What about the purple and crispy tips the cat didn't do that. Lol

Just looks to me like a cat chewed on you plant that is ripening and about ready to harvest. That purple is end of life fade. Can be a sign of a hungry plant if it’s not ready to chop. Is it harvest time? Can’t see buds well enough to tell.

If it were mine? I'd dial back the intensity a bit and feed it even less. Although color changes later in flower are quite common especially if your lights off temps drift into the upper 60's and can be more pronounced with even colder temps.

Edit: Full plant pictures would be extremely helpful.
