Watering frequency

Hi folks growing in HP promix with salt based nutes.

so my plants are 5 feet or so tall halfway through flower. And I have been feeding them 1 gal of water to 5 gal smart pot when they feel dry. My partner now has decided to feed them twice as often with half as much water . Seems like more work to me. My question is does changing the watering cycle like this have any benefit or is it more work? Will this have any adverse effect on the plant? thanks
