It's a mobile nutrient problem. Most likely a Micronurient. Magnesium, Calium, Zinc, etc. Most nutrient systems not specifically made for marijuana are lacking in the micronutrient area, and even many weed freindly companies lack them. I did a study once and found many generic nutrients are 20% off in they're numbers when it comes to weed. I'm a soil guy but I know ph is crucial for hydroponics. Is that right on?

up your feed strength the plant is just hungry.

youll notice the differance in a day or so once your feed strength is upped.
