Your girl is expressing an Mg deficit, soil ph is a bit low... run-off should range from 6.5/6.8. http://www.growweedeasy.com/magnesium-deficiency-cannabis
thanks codger.. that info was really helpful. i guess it is time to make a trip to home depot and pick up a bag of lime and a soil ph meter.i hope they still have some in stock it is winter now and their garden section usually sucks this time of year.
Be careful with the lime and make sure you have it divided out proportionately as lime can up your root-zone ph too much, then you'll experience Fe and Mn deficits, so be cautious.
