it's been a struggle, hang in there. impressed with your determination.
the switch of grow medium was a big decision, incisive, impressed again. i have had multiple failures myself, been there, done that - well, not what you've been through.
now that we've crossed that bridge - nurse as well as you can these plants back towards better health. these plants are typically quite hardy, take a lot of battering - of course it affects your yield/quality/appearance, but you can recover (given time, ofcourse). push then through flowering phase, to harvest. not to rush it through, but to get some results, to get some buds in your bowl. also, such rotation gives you a chance to start afresh with new batch/crop.
i'm not sure what's up with your DWC - you've put in much effort, and it seemed to me you were on the right path. don't get discouraged, like you did by switching to soil mix, try to find that which suits your growing conditions. you can always revisit DWC like you have planned, and things will be more smooth next time around. maybe you can explore other hydroponic setups - flood & drain, TFT, NFT, coco, etc. leave it alone for a while, concentrate on bringing these girls home.
i reckon soil mix generally is the most forgiving grow medium.
