Leaves losing color

I’m growing outside. Last week was extremely hot and humid. The sun was very intense as well.

If those leaves die, remove then as rotting leaves, in, near your bud can cause bud rot to start., especially if your humidity is to high. Cheers

Looks like heat/light stress and maybe a slight lack of nitrogen. Are you checking PH?

White leafs at the tip generally suggest light bleaching, try moving the light a bit higher.
