this is what is happening to several of my plants, what is the problem

They just may be shivering from the cold - actually they could be just huddling together to preserve moisture?

NOT COLD we have had HOT DRY weather since June

It is why I attached the icon, Doris, I know how hot it has been......

Doris i have the same thing with some of mine outside full sun rain everyday and no fert. in 2 months but was a time release of about 3 months.

i know my soil has been flushed several times!!

i dont have bugs or ants

now the stems are a bit greener then i would like to see. they are growing kind of fast.

some of my leaves are turning yellow but they are the farthest down the plants and i think mine is just natural they dont keep all leaves all year.
