Curling leaves

Typically, when I see leaves doing this—where the edges start to curl up slightly while the tip itself points downward—it’s often a response to too much light. When plants are getting hit with more intensity than they can handle, they sometimes react this way to reduce surface area exposure and protect themselves. However, based on what you mentioned in your other question, this could also be another symptom of nitrogen toxicity. When plants take in too much nitrogen, they can start to claw like this, and in some cases, the excess nitrogen can even cause lockouts of other nutrients, making the leaves react in different ways. It could be that you’re dealing with both too much light and the start of a nutrient imbalance at the same time. To dial this in, I’d take a look at both factors—if your light is running too intense, you might try raising it or dimming slightly to see if the plant relaxes. At the same time, checking your runoff EC and pH will help confirm if the excess nitrogen is causing other uptake issues. If that’s the case, backing off on nitrogen a bit could help bring things back into balance. Either way, your plants are still looking good, and catching these signs early means you’re on the right track!
