I agree.
One exception. Certain strains will turn fall colors. Purple, red, brown, yellow, etc. It will be genetic and even though the leaves are yellow they will be healthy and soft to the touch.
That's the exception tongue rule and easy to tell the difference.
Cooler temps can bring those colors out.
I agree with you. My statement only applies to a few strains. Just saying not all yellow means death or is bad.
This is an auto and autos sometimes tend to yellow and turn colors when they are ripe.
