Bring your pH up to like 6.5-6.8 your locking out some micro nutrients.

Hydroponics uses a pH low like 5.8 maybe you were confused?

edit: I was thinking Calcium before and I'm pretty sure now...

Calcium gets locked out of soil growing at ph levels of 2.0- 6.4
Calcium is absorbed best in soil at a ph level of 6.5-9.1 (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a
Calcium Deficiency

Calcium deficiency example:
