What are pH and ppm (500 scale)?
Any good fertilizer should produce no deficiencies (except possibly CalMag) when correctly used with proper pH.

yes, an in-pot pH should be taken.... P defc. and Ca defc. can also look alike sometimes.... T and RH% are OK.... What are you growing in? We need nute info too dosage, etc.,....
