Is somebody hungry or what?

Hi Bro, those scratches seem to be mechanical and are 2/3 days old 'cause they are already healed, probably made at the birth of that pair of leaves (the damage is mirrored) . Second hypothesis caterpillars, as they start to eat from the edges. But stay relaxed for Bubblegum, these holes will not hurt growing in any way and the leave will not fall. Pay attention instead to jack herer because the seedling is very small. Consider the fun of critter hunting. 👊

Yeah caterpillars, slugs and big stuff like that will wreak havoc on little plants. You can plant companion plants that will draw in predators that eat your pest. Just have to go out late at night and see what’s munching out lol. Then just do a little research whether you go that route or something a little harsher. Hope that helps and happy growing!
