Weird leaf twisting. K deficient?

My plants are 5 weeks into flower (growing in coco/perlite), and I am noticing leaf twisting on a lot of small fan leaves and sugar leaves. I also noticed some brown spots on a couple large fan leaves, and leaves with other deformities (like missing lobes, missing tips, two lobes growing stuck together,...).

My pH has been 5.8-6.0 and I had been watering everyday with a 500ppm nutrient solution, starting from RO water . I add about 100ppm of CalMag and then add about 400ppm of base nutrients. Any ideas? No signs of bugs, even under magnification.

What pics you posted (except for the first one) look like damage from moving them about. The first one looks like it's possibly a Phosphorous deficiency. But with only one leaf as an example and no idea from where I can't really tell.

I had something very similar happen to my current og kush grow you can check my grow log. I've been feeding with half nutes strength every other water(worried about overfeeding since I ran into this problem last grow). I will be going to full strength and maybe this will stop the issue I'll let you know. I'm using sensi grow nutes. I had some spots that could be a cal/mag deficiency telling me to up the nutes.

Did you use an eye glass or a microscope? Not trying to panic you but cyclomen are super small. You can't see with an eye glass.. Your plants don't look too bad though, not like they would if you had a bad BM infestation..
