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 bad5y ago

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!Week 4
