My First Grow with Fabric Pots...

It looking like I'm watering/feeding less with the fabric bags 5 gallon bags that actually hold 4 gallons with Sunshine Mix 4 with growstones mixed 2-1 I thought it was going to dry out really fast. They're really really perky in the morning but after 4 days after watering they'll be drooping after about 11 hour of light but then really perky again the next day till after another 11 hours of light is this because the roots are drying out on the outside of the bag?

Are you using trays with your cloth pots? It's hard to get the center wet without them.
