Novice outdoor, in ground grower. The plant was perfectly fine until last week. Not too sure what is wrong/ missing? I have researched all the common problems however it does not seem to fit any in particular.

With no information other than the pictures I grow the same way so if soil water and newts are correct how about heat I've been adding armor si from general organic that is a tip from some one on this site

Have you done a detailed search for bugs? Top and bottom of leaves, look for bugs and eggs. You will need a magnifying glass at least.

CATFISH22 has the right idea. Check for insects with a loupe or magnifying glass
