Hello community I’m hoping some of you might be able to point me in the right direction. Spouted this bag seed may 17
Had a rough start as its my first time growing. Noticed after I tried to do some LST , she started to show some holes and discolouration around the holes. Is it pests or stress ? I’ve looked for pests and couldn’t notice anything.
