Hi all, Thank you for your help! Could you please share your insights on these plants? Coco & GH nutes. Plants had minor leaf browning so I thought it was nute burn. I FLUSHED them 3x pot volume with plain ph'd water then gave them 1/4 strength nutes, upped it to 1/2 and now moving towards full. I was told I likely had Cal or Mag def, so I started using Cal/Mag (even though these plants are on well water ~140 out of ground). Running feed pH at ~5.7. Some people say nute burn, so I flush it. (these dark rust spots developed after doing so) Others say Calcium or Mag deficient... (started adding cal/mag but isn't getting much better so I'm at a loss). THANK YOU!
