Thanks a lot for the reply You did just what I needed and verified the problem. I have been flushing for water for about a week and a half and it stopped the problem but I dont think those leaves are going to come back. How did you think my plants are looking? I know the pics arent the greatest they were on my phone, but I am just worried that Im not doin something right. Oh by the way that was a Kick ass thread you had gion there for your first NFT system man I read that thing in about 20minutes and then read it again NICE GROW man!! I learned a lot from your thread and after seeing your progress and looking at my plants I think they should be bigger. Any help would be appreciated greatly from Anyone willing to post!!!
