Looks like ca *and* mg def (mostly ca, though). I'd say increase calmag if you're using it, otherwise treat with 1/4-1/2 tsp epsom salt and 1/2 tsp gypsum (but, gypsum doesn't dissolve entirely. Probably better not to let the sediment pour out onto the soil where it would continue to contribute over time when it won't be as much in your control.).
However, before doing that I'd make sure you aren't suffering salt buildup. It's about the right time for it. Have you been measuring your runoff ppm and ph? As a one time measure, runoff ph isn't too helpful. But, as a trend it's informative. If it's getting down around 5.2 it would cause this. You'd also see runoff ppms around 2500. But, again, it's more the trend. Those numbers may not apply to everyone.
If you have that problem and add more salts it will increase the problem (unless you water for 50% runoff which would make it more like an equal trade of fresh salts for those you flush out). If unsure, "it wouldn't hurt to feed just the epsom and gypsum with 100% runoff. That would kill two birds with one stone. I dont' think I'd increase the nute strength. I don't see that kind of deficiency. And, considering the odds are salt buildup, would make things worse.
