HELP!!. WHAT IS THIS ? Cupping leaves

Hello party people. So check it. I'm having some major praying of my leaves whenever I feed. I'm using gh calmag and allpurpose maxsea 16-16-16. My ph is consistently between 6.4-6.5. Is my ph off. Or is it too hot ? Over watering maybe. The leaves look like tacos. All of em r In 35 gal grow pots. Any advice woul greatly b appreciated.​

I ran across this problem last week with my 3wk old plants, come to fine out I had the light to close and to hot, I moved it up a today they look fine...

This is all outdoor. Not indoor

The praying is twice a bad when I feed

How often do you water/feed? Have you recently moved them from indoors to outdoors, or did they start outside?

I've noticed this in my past outdoor grows when I don't water enough, and it seemed like the heat of the sun after a good water would cause the leaves to cup like that seemingly to remain cool.

Can you shade them for a couple hours before your next water, and see if the problem is as bad?

Your pH is good fwiw.

If it is a deficiency, I've never seen one like that.

I feed on Tuesday and water on Friday. And they have been outside for months. It's only when I feed that they cup worse then whats in those pictures. When I use straight ph water, they don't.
