Ebb n flow with coir night cycle feed?

[WannaBeGreenThumbz]

I see so many saying they don't feed at night as it's not needed but I know at the same time I'm not supposed to let my coir dry out as it will leave salt build up and being week 5 flower and them drinking more and more it definitely concerns me going 12 hours without feeding, is it different with my system and medium?

Don’t let Coir dry out regardless of time of the day. May not be optimal to water at night but better than having a salty medium and dead root hairs
