They are only on one plant and on that plant I found it on the leaves near where come together, and deep in the new baby leaves. I treated with organibliss (neem extract) not sure if that will help or not. Plant seems completely unaffected.
Yeah I topfed right into the plug, added a smidge to the water supply and gave them a light spritz. they're very young plants and I am considering just going through with tweezers and removing the ?larvae?.
to me it looks like dried up cannabis sap. small fractures to the plant where fluid can exsposed to air and harden. doubt it is bugs have seen simular before.
edit: when u pull it off does it crumble like dried sap? clearish
