Under watering

So I got 5 gsc auto’s in a 5x5 with 2 philzon 1200 led. There in 5 gal fabric pots with a peat mix. With dry amendments
So my day temps are Around 75 and my night temps around 69 right now. Rh is 63.
So these girls are in week 5 and just seems like there never drying out I’m only watering half gal each once a week. The plants look good and all I’m just wondering if I should just keep feeding like that or if I could bump it up 2 twice a week

Wait til the top inch of soil is dried out before watering again. Overwatering is worse than under watering

There deff not over watered, it just seems to be taking forever to dry up. But this is my first grow in peat mix

At that stage with that size pot. yes it will take that long to dry out. Are those 5’s?

Four pounds of water a week at that age, in 5 gal. fabrics is a little off but they look great. I use the same size pots with a light
airy mix,1/3rd. perlite, elevate pots, provide air circulation and require 1/2 gal. every 3-4 days at that age for a comparison.
I think they're developing roots and will require more soon. You can't OVER water a well draining medium. The problems
begin when you water too OFTEN, replacing oxygen pockets with moisture and drowning the roots. Good luck

Just used to watering everyday or every other I guess prob will as they get further along. There like 4 weeks o my watered them 3 times or so n very lightly. Like I said I’m just used to having to water every day or so lol.
