yes you do have Phosphorous and Potassium deficiencies, but that doesnt mean you should harvest now. You can check the trichomes to see if the plant is ready, using a 40x minimum magnifier , cloudy or white means THC is present, clear means not ready yet and amber means you'll have more of a couch lock effect. otherwise you can check the pistills to see if you're ready, you're looking for something like 70/80% brown pistils. So no you're not ready to harvest, and you should probably add some PK and chelation agent for a week maybe two before a two week flush... sorry for the bad news, but it's the truth ! hope this helps ! 🚀
