    Strange Burns on Leaves, Please Help!

    Hello All

    These strange burns/marks have started appearing on one of my Hydroponics clones. Plant is about 3 weeks into veg. PH sitting at 6.2 with the right nurts with calcium top up added. Water Temp in the system sitting at about 22c

    Any advice please would be much appreciated.

    Those could be a result of PH fluctuations.

      I agree with PLreef, pH fluctuation most likely caused by algae in the reservoir causing the problems. One should keep the water temperature lower than 22° C, 20° C should be the maximum temperature of the water to keep the algae growth down.

          I'm going with old damage
          It's one plant on one area. There is also a pattern to the marks. Bugs and pH make random marks. All of the edges of the leaves look about the same age. The edges are sharp meaning nothing is actively killing your leaves from the dead side to the green.
          Is it the light or are some of your leaf edges off color?
