@ToadieK, Yea I noticed the ph was a little low. Think I'm gonna try to up it with some limestone powder, hope that'll get rid of the yellow/brown leafs.
@Pieter710, You're growing in soil, so I would try to get the ph into the 6.2-6.9 range. Uptake of phosphorus, calcium, magnesium, and molybdenum are all affected by low ph.
