I am hoping someone can tell me how to make this plant look normal again. This is the only one that we have that looks like this.
Wow I've never seen one that badly curled before...it looks like a combination of things maybe. pH issue, heat stress, overfed? Weird that's the only one. Are the others the same strain? There has to be something done differently to this one than the rest you're forgetting. Here's a thread with a similar problem Leaves Curling Up, Dry and Get Orange. Please Help!!!
Looks like Heat Stress & possibly lack of Nitrogen. I have attached a leaf deficiency/identification diagram. SUPER helpful to get a basic idea of future issues
If it is the ONLY one in a large garden.... is it on the edge of the garden? could have been infected by bugs that just haven't made their way to other plants.......yet
