Mine started to do that just before flowering started. I thought chemical burn from to much nutrients. So I flushed it and pulled the couple damaged leafs. Everything good now. I noticed a couple other leaves on your plant have whole from bugs. Hopefully it’s nothing major and everything goes well for ya.
Yeah I noticed that to just not sure what to use that is safe to fight off bugs during flower.
the thing that gets me is these plants are being feed the same and it’s only this one that looks not so nice Even the green is much lighter .
I did add some food to plants last night maybe I’ll try something that acts faster because all I’m really using is dry slow release fertilizer Gaia green
