Being in Spain I would look at nitrate levels for the tap water you are using. I believe it’s due to aggressive farming and the way the water table works in Spain. I say this because you are describing a chemical smell that usually comes from over fertilizing.
I would suggest, if this is the problem, finding a different way to water when you flip to 12/12. One possibility is using RO water only during the 12/12 stage.
