    Off green patches and deteriorating leaves


    7 week old girls in coco, just switched to 12 12 less than a week ago. They were looking extremely happy, one has now developed these off green patches on lower leaves and the patches seem to go "see through" and eventually cracks/ break.

    PH is 6.1.

    I am on an all in one nutrient - picture attached, with cal mag as well.

    Temperature has been around 25c but extremely humid (75 -85), I have a dehumidifier on the way.

    Also I maybe spilt some nutes on these lower leaves, not sure if that's an issue.

    Any ideas on these funny patches??

      I dont grow in coco, but what I see is a PH issue. Doing a bug check is always good, use a 30x zoom or greater lens, look at the under side of every leaf..
