    Default Black tips on leaves

    Paging dr greenthumb!

    I have recently noticed black spots on some of my Hell's OG leaf tips. I am feeding, a combination of Biobizz, calmag, molasses and Ph 6.0. Originally I though it was a phosphorus deficiency, but the Biobizz should be sufficient enough. Then I thought it could be calcium, but the problem persisted when I started adding calmag.

    My soil is organic living earth soil blend.

    Any idea what this could be? Your help will be dearly appreciated!!Click image for larger version.

    Looks like nothing but some other markings on those leaves would make me have a close look for bugs at the 1mm scale. Could all be nothing

    Might be best to identify what the bug is, if at all but in general pyrethrins is a good organic solution for most things.
