the reason why i water them everyday is because everyday the soil is bone dry so i give 3/4 gallon water per gallon grow bag.I thought
i was doing the right thing,sorry im new to this but they are growing big and fast
Grow bag is above ground, I guess? If so, it might use more water than if it were in the ground. You are checking soil moisture every day, I guess, by putting hands in soil and digging around.
Size of plant matters for when and how much to water. If they are still small, water should be made available in the "few inches" range but very quickly, the plant will send roots deeper and you will want to back off daily watering. If they've been in the pot for more than a week and have shown some growth, maybe back off watering to every third day. Then really soak it. From what you say, they are doing OK and growing, so, let them dry out a few days and watch the plant, if it starts to droop then time to water.
A problem I have with containers is that above ground watering is tricky. Pour water on top and the water just flows out the bottom without wetting the soil. Also carries nutrients out. Drip irrigation solves this. A drip irrigation set up is available at Home Depot or just about any garden center. The dripper adds water slowly and allows it time to wet the soil. I'd use two half gallon per minute emitters and water for a couple of hours twice a week. A timer takes the human error out of it.
It's not too late to transfer to a garden plot but maybe that's not feasible for you. If you do transplant and are using organic methods, treat the roots with mycorrhizal fungi. Various brands are available. Great White is one and Myco-Fusion green 150 is another. Around my neck of the woods in mid Willamette Valley, Samurai Growers carries the MF product line from Santiam Organics. It wouldn't hurt to dig a hole alongside your plant and add a couple of tablespoons of the powder and lightly mix it into the soil. The spores have to touch a root to germinate so, a few exposed roots would be good. If you use conventional fertilizers, don't bother.
Earth worm castings worked into the surface are a good idea. Cover the top of the pot with a mulch, maybe moss or commercial compost.
I haven't used it but some people swear by this automatic watering system:
