Hello
@Rocstah ! The plants must have been really shocked ! What kind of hydro is this? It looks like with an under current system. First i was going to tell you to use some compost tea but i wouldn't like sugars running through my water pump ( if its an under current system ). If its some kind of DWC without water pumps then use some. It really helps with the root formation. Second apply some mycorrhiza to the roots. Third keep your water temperature at around 20-22 witch i can see you already doing it. Fourth if your plants are very stressed you can spray with some kelp extract. Happy growing ! 👊
