Stick your finger in the soil to just past your middle knuckle about 2 to 3 inches in if its not moist water. In a small container like that it may dry up quick maybe water every other day. Use nutes only once a week and you may want to wait until you at least have some 5 to 7 leafs or about 8 to 12 inches tall to add the nutes once a week.(They should be good on just water until they reach that size) Add them to your gallon of distilled water then PH Balance after adding the nutes, start off 1/2 to 3/4 what they call for on the nutes just to see how the plants will react.
