that one is doing something different for sure. looks almost like a nutrient problem .either it's a finicky eater, happens, or it was on the border of a pH level and something is locked out? or a hot spot in the soil who knows.

something's going on, looking at your tips might have the ppm at the border and this one doesn't like it.

they like it, this one doesn't.

I stopped growing different varieties in the same soup because of that

more educated minds will jump in I hope
