Diagnose This Please!

I have just recently tested the ph on the water discharge and it was in the 6.0 to 6.5 area. agian i am using humbolt nute organic. only going 1/2 strength. Thanks dudes and chicks.

don't flush, organic nute at half stregnth is not gonna burn your plants, your ph is fine too. my plants looked like this before, it was a potassium def
