Sounds like your envirionment is good but after she gets jacked up it can take 2wks or more to come around providing the cause has been attended to. As far as that goes, without complete details about your entire process to now, just too hard to tell. Are those the tds values after nutes are added? On your post info, does cond. mean conditioned water? If so, it may have sodium in it if resin in conditioner is old. Salt= girls. Ever checked the run-off water ph. If the soil has an off ph it can reduce or stop intake on some nutes. Looks like the signs to me. post up as detailed info as you can and a dirt wizard will guide you through it as I am far from it with the terra. Also is she in a 8-10 gallon bag? Usually a good flush takes about 3x pot/bag volume. should feel pretty light before watering again. If soggy and not just damp then I'm with TIP, your prob over-watering
