They say to never use nutes ever.. I am not sure about using half.. I will email them and ask them..Yeah I was wondering if u could use that same amount in a 5 gal pot to get a bigger root mass and still have enough to complete the autos life? Maybe get a little larger of a plant using the same amount? I'm just curious because I know the soil is made for photos so I'm wondering what corners we can cut and still get great results using the amount recommended for our life spans but whatever put size we choose? Like using nutes at 1/4 or half strength lol
