Look real close. there are some bugs will upload microscope photo soon but no indication of spider mites as there is no leaf damage or webs..these bugs have been present in low numbers the whole time however have not seen any detrimental effects to the plant
If you are in your final flush, quite frankly, I wouldn't worry too much. There is going to be some yellowing anyhow. I've been chasing this same rabbit with one of mine, and I originally thought Mg or K def. However after dosing some epsom salts and kelp, I started to think it was more of a salt build up, which looks fairly similar to K def... Again, you are almost finished. If it is Mg, you could add some epsom salts otherwise I would just continue flushing.
thanks for the info... i pretty much decided that the plan is to just let it die if its going to and harvest at that point...or harvest when its ready either way im sure it wont be too detrimental for quantity maybe just potency
