Something happened with these 2, and I've come up with 3 possibilities. #1 my humidity where I live has been extremely dry, humidity swings have already happened a couple times from my humidifier running empty, these 2 may have been more sensitive. #2 some dumby forgot to PH down his well water on these 2 the 2nd time he watered the pots (me) cause he's a space case. Other 2 strains are doing good. Or #3 soil got a bit too hot for them with worm castings in the bottom. Not sure, not much I can do except make sure I'm PHing correcting because it totally looks like PH wrinkle to me, and I've seen it before! But I swear I PH downed her 😅
