The light is around 24” at full strength, they are in 5 gallon pots now, it’s just strange it’s only the one doing it. The other doesn’t look great but it’s better then the onelooks like light stress and perhaps little overwatering. What's the light settings at? Strength + distance
I dont water till runoff anymore, I tend to find myself overwatering more often when I do that. I'd rather give a little bit (1/2 gal to a 3gal fabric pot) every 2nd/3rd day.
