Cannabis has a pretty high demand for nutrients for optimum production. They will grow just about anywhere like a true weed but what we want is an agricultural product. If your close to pine trees using a contained soil will help with pH. Checking the soil pH will let you know. May be wrong but the needles are what changes pH. The further from the tree the less the soil should be effected. Theres usually a line around them here where the needles end and grass/weeds start growing.
