Watering everyday a problem?

But when they are underwatered they also droop. So its hard to tell if you have an overwatering or underwatering problem.

And ive always heard its bad to water plants everyday. So just to be safe I try to water them every 2 days. But my soil is drying up so fast. I watered them with nutrient water for veg growth last night around 10pm for the first time. Im going to wait till tonight to see if the soil is dryed up below the soil because i felt the soil today and checked beneth the soil too. Still a bit moist. Which is good for now. Hopefully its still moist tonight and throughout the sencond day.
