Взрослые листья покрываются коричневыми пятнами

Hi. First off your water needs to stay really cool, to keep the slime from starting. I ran chillers with great success. Frozen water bottles or freezer pack in the bucket to cool things if you can't afford a chiller. Your nutes, how are you mixing, micro last always. I highly suggest a ph and tds monitor like the Growboss. For dwc and rdwc it is pretty much a must if you want great results. Your total ppm should be around 700 1.4 ec for this stage. That's total including your extra piranha and b52 and cal/mg. Always mix your micro last to reach your total. Hope this helps. Cheers
