:thumbsup:'shake just gave you the best rule of thumb, pick the container up...you can tell when it's light, then it needs watering. And when you feed or just water, soak it good, you can't overwater at this point.

But since you mentioned using a soiless mix, I would assume Pro-Mix or Sunshine Mix, then you would probably want a PH of about 6 (+/-.2). Check and see if the ferts mfg has a recommendation for both ph and water/feed schedule though.

good luck with it!
