It can. I have a hrdro set up, and one plant didn't get enough light for a day or 2 and it's leaves are droopy. See i focused on the plant that had buds, but she started to sprout a few hairs yesterday, so i put some light on it, hoping to revive it.
how will a stick give it even light..i checked em out today after work....so droopy theyr not lookin good im startin to get worried..could underwatering be the problem??
