Could be a pH or micronutrient problem. Are you sure your pH is 6.0?

My last test showed 6.0 I'll run another today...

What I'm seeing is lighter colored growing points. Sometimes this is from fast growth — plants don't form chlorophyll until they're hit by light. If the plant is having a growth spurt, sometimes the chlorophyll production lags.

Sometimes it's from a micronutrient deficiency or lockout. If it's lockout, it's often from pH, but it could also be from an over-abundance of something like calcium. I hate to tell someone to try and change the chemistry of their soil, as this is a difficult thing. You could do a few foliar sprays with a nute containing iron and zinc, without causing problems. But as I said, this might be nothing.
