I have a couple of plants that have some strange spots starting to appear on the fan leaves. I cant figure out what is going on. I am using Fox Farms Ocean Forest and this particular plant is under 2 4ft flouros and a couple of leds. I am having this same issue with 3 plants that are in flowering I just cant take pics right now because they are on dark time. In Flowering I am using a 400 watt Hps. Temp is around 85 in flower and low 80s in veg. I have a feeling its some kind of nute lockout but I am not an expert and need expert advise. Attached is a pic of one of the veg plants.
