The one with the curly leaves I actual didn't water for days until it drooped worse than that because I thought it might be from overwatering. So I'm guessing a nitrogen toxicity but just flushing with only water didn't help so not sure what to do...These plants are overwatered. These big pots are holding a lot of water. How often are you watering/ feeding?
Thanks bud! Pun intended lol and yes, soil.You are in soil right? I water/ feed every 5-6 days in 3 gallon pots all the way through flower....and I cycle my watering and feeding to 3 watering -1 feed....and I have no issues. See how your fan leaves are all turning down on the tips (chicken clawed look). With your root zone wet all the time, and not allowing the root hairs to get oxygen, and this will affect the uptake of any nutrients the plants require. Let these plants dry out more between watering/ feedings.
