low k, i'd bet. low p doesn't progress like that. image search and download a nice clear, high-resolution 'marijuana leaf symptom chart' https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg That's an image-only link so no website will load... from a common marijuana site, so it's safe... can duckduck go image search if you want and get the same high res image elsewhere, too. As you can see high p might cause some burnt serated tips but not low p. also, the general lushness of this plant look like it needs more, not less. And doesn'tlook like a pH problem because there isn't a whole smorgasborg of symptoms coinciding.... So, I'd conlcude it's Low K. Try to up that without changing levels of other nutritional elements as best you can. Necrotic/burnt damage does not heal, but chlorosis can become a healthy green again. I don't see any clawing here. Maybe hesi is a bit too high in N? Maybe you just need to use less than instructed.. time will tell. Think more than just N can cause clawing, too, but is most commonly high N. obsserve and adjust.. fertilization is about everything you've done since it sprouted... how you feed in vege can impact needs in flower, so there's a whole lot of variability here. Be sytematic, take notes... adjust intelligently and within a grow or 2 you should have a very good process that avoids most issues. Some symptoms late in flower are inevitable at times. As long as it isn't taking a nose-dive, easy enough to adjust with a small change.
