Promix would be my suggestion. I don't have pH issues and in fact, I recycle my promix up to three times with no problems at all.To be honest, I picked it up to avoid the PH issues associated with soil and have had trouble with it all along the way. I've changed out nutes three times assuming that was the problem. I have a good lamp, lots of circulation, and I check on 'em every single night. I've seen people use mediums such as powdered rockwool and pro-mix. I just can't seem to get it right, though it seems like it should be so simple. Maybe I should go back to dirt.
In regards to your unhealthy leaves, I'd point to your process (perlite hempy), not the plant food. Moving forward, this is what I'd do if those were my plants. I'd rip off the 'dish' on the bottoms of those posts or drill holes in the bottom of them and I'd run them like 'drain to waste'. Feed at close to 1 tsp/gallon grow and protekt and I'd imagine you'd need to water nearly every day.
