Check that the first points of the A-PAR and Gs-VPD curve have a high value for A / Gs. We make the light curve after the Rh curve; there is a possibility of having stressed the stomata (also because we close the stomata during the previous curve). We can use the points from the A-Ci curves (the first points at 400 ppm) instead if needed.
