Could someone give me a hint as to what's wrong with these plants?

I am relatively experienced but this is my first outdoor grow.

Indica dominant bag seed growing outdoors in the California sun in regular topsoil. I always water w. PH corrected water and started some light GH nutes a couple of weeks ago. Soil PH is quite a bit higher than what's optimal so I keep the water around 6.2 to counter that a bit without going overboard. They have been in this soil for at least a month now. Before replanting they looked normal and healthy.

Does this look like a PH problem/symptom? Usually I just see curly leaves when it's PH, not the folding up that you see here?

Or is it heat related because Indicas don't like heat? (we have 95 to 100 these days and low humidity.

Any other ideas?
