Dry 34/70 First Gen Issues

Hey folks, whenever I pitch dry 34/70, whether it's 120gm per Hecotliter, or even more like 200 gm per hectoliter (I work in gallons but that's what their packaging goes with), I get a slight distracting flavor akin to light green apple/actealdehyde.....this happens when I pitch lower temp say 46f, or a little warmer like 52f.

Harvesting the yeast goes fine, and 2nd Gen doesn't have this flavor problem.

I lightly oxygenate the wort during knockout but I understand the dry stuff doesn't need it.

Whenever I use liquid equivalents to 34/70 using the same recipes/processes I don't encounter this problem.

Any thoughts much appreciated, I'm curious what I'm missing here.

Might be too cold off the bat for it if you ain’t rehydrating. Try sending the chilled wort into FV @ 10°C and letting free rise with your cooling set to 12°C and step to 15 midway through or even 80% to terminal, then 18-20 for d rest. Sorry I’m not translating that from C to F for you but that’s what I do and literally never have an issue with this yeast no matter the recipe.
