I recieved a marijuana plant from a friend, I transplanted it in a field next to the house for security reasons. This is my first plant, I need to know how much water and fertalizer to give it! First I planted it in good soil from my garden, then I've been giving it 1 Gallon of water/day and 1x a week I've been giving it multipurpose mericle grow. It seems to be doing ok! What do you think?
