    Default What do these spots / marks mean please?

    Hi there,

    Could anyone tell me what this discolouration means, please? And what remedies may be needed?

    A good percentage of the leaves have these spots like this to varying degrees. The plants are in the second week of bloom are being fed Canna A+B with Mighty Bloom Enhance.

    The spots are lighter / whiter than the rusty brown that usually comes with magnesium or calcium deficiency (according to my Canna First Aid guidance).

    Could it be stress? I had to move a few things around - including the plants - to fix some issues in the tent.

    Thank you

    As said, some sort of bug... thrips would be the main culprit

    Looks like thrips as noted above, check out thrips in Google under thrips on marijuana and how to get rid of them.

    Ive seen those on outdoor plants but never in my tent. Do you grow any other plants nearby that might attract thrips?

    Current grow - OGKZ / GZ / LSD / 750w lm301b
