If Potassium is the issue, and particularly in flowering phase, add something like Armor Si, or you could also add a complete base nutrient like Floranova Bloom. I am seeing yellowing between the veins like bars, particularly in that first picture, but I can also see how it also looks similar to a K deficiency in the next few pics. You can provide your opinion without being insultive and, generally, people are much more receptive to it when you're not. I'm not sure I've ever met anyone who enjoys speaking with an asshole, even if the advice they're providing is good.
As for the OP, if you're still on the fence on what this could be, you have a couple of options. You can foliar feed epsoms in flower, however it is at an increased likelihood of mold related problems occuring. If you've lots of good air flow, this likely won't be an issue for you. It's really not that hard to avoid contact with buds when spraying your foliar feed. I don't foliar feed often at all, but I have foliar fed epsoms during the bloom phase with absolutely no problems AT ALL (and subsequently smoked the bud, no problems). If you were going to foliar feed a CalMag product, I would caution against that. If this makes absolutely no difference, or if it even makes the problem worse, you can discontinue foliar feeding and walk away relatively sure that it's not Mg deficiency. You could also water the plants with epsom salts if your humidity and air circulation makes foliar feeding not such a good option. Your other option would be to supplement your plant with potassium if you find that the epsom salts don't help, or if you simply suspect it more likely to be a K def than a Mg def. As I mentioned earlier, Armor Si is a good K containing supplement that also happens to be of great benefit in flower. You could also add a little bit of FloraBloom out of the FloraTrio line up, as it contains little to no N. Something like Floranova Bloom (1 part base nutrient) would certainly work, but it does have a little bit of N in it.
Good luck, and please keep us informed as to what brings your plant back to normal for the sake of future readers, and so that if it doesn't help, we can try and figure it out.
