3wks into flower deficiency or salt buildup?

What and how much have you been feeding?

I'e been following the FoxFarm Nutrient line the pics I took the other day is when I flushed it with a gallon and half water with 1/4 recommended nudes. I had flushed it with a gallon regular Ph'd water couple days prior to flushing with the gallon and half. I just fed her today with a gallon of phd water full recommended nutes
