Re-pot both into clean compost. Less watering for the Pelargoniums, I would
suggest. But the compost on both must be exhausted by now.

The feeding should have counteracted that. My guess would be the
watering - pelargoniums are remarkably resistant to drought.

It's never a good idea to 'water twice a week' - watering should always
be according to the needs of the plant, more in good weather, less in
damp cloudy weather. Nothing wrong in having a fixed schedule for
examining the plant (saves forgetting about it and returning to find it
shrivelled) but looking at it doesn't mean you have to water it.
