Hi
@RyukyuFarmer! I guess you meant "2ml/L" ? Manufacturer says it is "extremely concentrated" and advise to "start at a lower dose and work your way up". Considering you're growing an autoflowering strain, you shouldn't feed with such nutrients, or do it step by step, starting with 1/4 of the recommended doses. Now as an emergency move, I would flush the soil for a few days with plain pH'd water and see how it goes. Hope this helps, keep us up-to-date and good luck!
