to be of assistance it sound like you have a bit of build up in your medium. If you u have the means, you should check your runoff and see your ph and tds, assuming your in soil. From there you can really determine your problem, but it sounds like a bit of nut burn. You should flush your medium at least three times the volume of your container with reverse osmosis 7.0 water and things should start looking better. If your still getting lots of yellowing then u have nitrogen def, and i would recommend a bit of a great plant aid product called Revive by Advanced Nutrients. On the other hand, i myself have been striving to learn and perfect dj shorts true strains and have found that the majority of the dj line dont like nutes, they are very sensitive, and burn easily if not monitered. They simply grow the best organically with no additives. Dj is all about old school organic dirt growing and his strains are geared towards this, hence old school......Dirt....people are gonna hate but i say fuck hydro and nuts, srry im getting off subject...lol And btw the crinkle you see on a couple of your krushes, totally normal my friend. Its a trait common within the dj line. its actually a way u know u got a true strain. hope this helps!
