have you checked for bugs on the underside of leaf in pic # 2 and 3? looks like could be leaf miner but could really be anything. last pic- your plant looks good and healthy. I would not stop the nutes, especially since she just entered flowering and judging my her lighter shade of green, she may go deficient if you withhold for too long. fine dolomite lime will really help by buffering the ph of the soil and providing any extra ca and mg if needed.
are you feeding her at half stregnth?
