If that's at canopy level, at least 25c would be nice. 22 at their ankles might pass, but the buds want to be a lot warmer. Think about how you perform differently at 22 to 28. It's a long way off. I wouldn't expect to see much happening, at 22c.

Are your plants running a little light green from N reduction. Are your seeing the K signs of outer margins loosing colour, but not the new leaves. Are the tops a bit too soft. Are you seeing Mg signs, that don't quite seem right. These are all expectations from cold at damaging levels. Beyond mere losses that wouldn't show until the scales spoke.

It's the time of year for K issues. Or rather, a lowering of transpiration. It must be this months most popular ailment
