Trouble is, with overnuting your plants... esp. in DWC, is that you get large build-ups of salts in your media. The build-ups in your plants can also cause deficiencies in other nutrients.
This is why def' is so hard to call... as it could be over nute. You have signs of both. Your EC is too high.
Your EC should build slowly from 0.4 ec for seedlings, right up to 1.8-2.0 EC at the MID-FLOWER point (this is very dependent upon strain/phenotype). After the mid-flower point you take the EC back down again slowly to around 1.4 by the time you flush.
Plants can only take in so much nutrients at certain stages of growth.
