Not sure about deficiency, thought was Calcium or Magnesium but not sure anymore.The nutrient deficiency is back so I gave it another double dose of CalMag to see if that can stop it in its tracks but I am not positive if that is the specific problem. Added micronutrients mix as well to see if maybe that helps. Any suggestions would be appreciated.

K deficiency almost wiped out this plant. What do I do now?I’m somewhere between 2-3 weeks until harvest time should be. It’s day 80 from seed on this autoflower. Had a bad potassium deficiency that I didn’t figure out quite in time and I’m not sure if too much damage has been done. What should I do?

My plants are suffering a Phosphorus deficiancy due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. what should I do? I went to check on them today and the amount of damage they took in 24 hours was bad.5y ago

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?Week 4

Flushing don't seem to solve my lockoutIt's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout.
I flushed 2 days ago but she keeps getting worse. Am I being impatient?
I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.
