Hey guys, my plants are starting to canoe, but it's definitely not heat stress (temp is about 78 F). What's going on here? I had an indica that did this and then went on to gnarl up and die. I just transplanted to clean soil last night (no nutrients, plenty of perlite, sterilized), so it shouldn't be a soil problem. Additionally, I'm using bottled water (not spring water) and the pH seems alright (about 7 or a bit lower). What's going on here? Here is another picture, but this one is definitely nute-burned looks like.
