Yellowing and brown spots on leaves Can anyone identify why this is happening? I am growing 2 other plants (one the same strain) with identical treatment and this started happening with one of my Royal Jacks. Everyday new leafs show the same symptoms.

I think my plants are suffering a Phosphorus deficiency 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. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Flushing don't seem to solve my lockout It'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.
