Its a potassium deficiency. Plants in flower will start to require more phosphorus and potassium then they do in veg.

You said feeding was at about 700 ppm and 6.5 pH? A lack of a specific nutrient doesn't always mean it doesn't have enough, sometimes something else is locking it out. Just be careful before making major changes.
