So I noticed some light spotting/discolouration on the upper leaves of Samus. I've never seen anything like it before but is it normal or something to freak out about? Are the leaves mottling?
I've got no idea what it was but a few leaves showed up with holes. A couple of small ones and some longer. Some see through spots showed up too so reckon there was defo something munching away in there. I've sprayed down both sides with a pest controller and defoliated the worst affected. Seems to have worked so far!
Have you checked the underneath side of the leaf? Could you have spider mites? I don't think this is a nutrient problem... If there are no signs of any bugs of any kind, I wouldn't worry at all about this!
I've done a full rundown but can't see any evidence of mites other than the spotting. It seems to be stemming from the leaf midrib and veins. It's also very localised and only affecting the one plant even though its touching the others. Tis a headscratcher so may just have to wait and update
