Roundup (glyphosate) is systemic ie it travels through the entire sytem.
Therefore the entire plant reacts to the element introduced, if Roundup
is used to strength death by dehydration. You can use varying doses for
different effects, I have heard of a greenkeeper using a very weak
solution to retard the growth of bowling greens during periods of
abundant growth. Reaction is also affected by plant activity, during
drought the uptake is reduced.

The leaf symptoms sound like plant stress from any number of factors.
