Talking about indicators of ripeness

I am aware of 4 indicators: Swollen calyx, darkening and curling pistils, the color of trichomes (clear -> grey -> amber), the decaying of surrounding leaves. Did I miss any?

Now the main question I have here is what indicator is better if they aren't all sending the same signal?

For example a plant with decaying leaves and 95% darkened curled pistils but only about 5% amber trichomes or fewer and a 50/50 mix of swollen calyxes.

Also should a calyx ever turn brown itself or does that represent a problem?

A brown calyx is dead and could turn moldy. You don't usually see them unless the plant is past peak.

I mainly harvest by the glands and calyx.
