I wouldnt sweat it unless you have serious heat problems. My best grows ever have come off those dwc plants after growing in soil forever. I still grow in soil for the ease but I gotta have hydroponics going to on fact alone of how fast they grow and big they get.
Pm is such a problem for basement growers....not sure if this is you. If it were me, I would scrap the entire grow...clean and start over....but that's me. Environment is such a vital role in growing and sadly one of the most overlooked parts of a grow.
There was a point my 6 dwc in late flower were chugging 10+ gallons a day of water and nutrients between all 6. Major PITA but harvest was well worth it. I have even ran DWC full grows without ever changing the res water once because of the water turnover rate of water used in hydroponic plants...
I actually don't grow for profit either. This will all get jarred and will cure damn near til mid way next year. I have a pretty vast collection of strains grown over the years perpetually. Ya know what they say about a friend with weed hahaha
