The problem is too much nitrogen. I suggest you use pure water for the next 1-2 weeks.

Sulfur def. pale green with a downward hook.
lower P.h. below 6
add 1/2 teaspoon epsom salt per gal next time you water.

looks fine to me, i'd say the color of ur leaves is the most important. if super green that seems healthy.

spots, yellow and holes are what you dont want.
