    Magnesium deficiency?

    Ummm...haha you ain't gonna like this, I don't know what scale, it's whatever my Milwaukee probe is set at.

    Magnesium deficiency?

    Its definitely on the upper parts of the plant. IR thermometer reads about 74° at canopy, is that enough to cause light burn? That part in the picture is about 40cm from the light.
