Yes, different juices have different heat tolerances via wattage and atty ohm used.
NETS especially because they tend to contain more organic particulates ( they are extractions after all) are therefore sensitive to higher temps.
The amount of PG, VG and DW will also affect temp ranges for juice.
I would expect juices with higher PG and H20 concentrations to be more tolerable to higher wattage.
Adding either of those two to your juice in very small percentages may make them more agreeable to higher wattages, although flavor will also diminish...another great reason for doing DIY.
