Can mean sulfur deficiency, but appears as a 'normal' petiole color in some lines. I think the leaves look a little on the pale side, though, and would do a soil runoff pH test to rule out lockouts as a cause, and flush and start feeding with a complete cannabis specific veg fert if you haven't been.
