Re: Plants are showing nutrient deficiencies. What is the best way to correct this? [Re: phychotron] #845899 - 07/07/20 07:27 AM (4 years, 5 months ago)
So after looking thru that chart it looks like they are lacking Nitrogen, Magnesium, and Potassium. So I need to check my soil PH and hopefully can get something to help get back on track.
