'shift down' is a correct and usable term in written English.

We need high levels of hormones to reproduce, but we shift down to a lower level for the second half of life.
Then, the fluid composition will shift down from the point A to the new equilibrium point B shown in Fig. 7, resulting in the formation of tremolite.
In addition, the direct/indirect Eg value of Ge which was determined as 1.15/0.72 eV is observed to shift down by a 0.13/0.42 and by a 0.23/0.54 eV for the Ge/MgO and Ge/BN devices, respectively.
Both resonances shift down-field in the presence of donor analytes and the observed shifts (0 to 1 ppm) correlate with the basicity of a variety of added Lewis bases, including TNT.
Besides the nutritional stimuli (nutritional shift-down), studies have identified several environmental cues that induce secondary metabolism, as well as the mechanisms by which these signals are sensed and transduced, to activate regulatory networks.
Membrane potential and intracellular ATP level were measured as early as 4 days after the anaerobic shift-down, where M. tuberculosis viability at both pH is still comparable (Fig. 2A).
There is significant experimental evidence that the transcriptional regulator devR (also called dosR) is a key factor in the metabolic shift-down to non-replicative persistence (see Discussion).
The reduced synthesis of ribosomal proteins is indicative of adaptation to a slower growth rate following recovery from a nutritional shift-down.
