Can anyone help me with this problem?? It has been happening for awhile now... This starts then it stops for a little bit and the plant looks great and healthy. Then it starts again. The only thing I can see that may have been a problem is me adjusting the ph to 5.5 everyday. From new info I have been reading it should be more like 5.8 - 6.0. So maybe a too acidic ph is causing nute lockout and this burning. I have started to just keep the res at 5.8-6.0 ph. How long until I would notice a change? I have seen other pictures of this alot on the internet but no one every says what it is or how to fix it. In the history of growing I can't believe NO ONE has ever had this problem and found a solution for it. If anyone knows what this is let me know please. It doesn't look to match any of the symptom pictures at the top of this forum.
