Like any living thing, a nutritious lifestyle is a must for success.
Cannabis plants are not exempt from this. Cannabis and hemp plants need a very specific set of nutrients and ratios to thrive. These nutrients are nitrogen, phosphorus, and potassium. Nutrient-rich soils will usually contain enough of these nutrients in the right ratios to feed your plant for about three months.
After three months though, you might notice the leaves of the plant starting to turn yellow or the stems on your leaves turning red or different colors on the leaves. These are usually symptoms of some sort of nutrient deficiency.
You can purchase seeds from a seed bank. I got mine from Home Grown Cannabis Co., they have a wide range of seeds available to choose from. I choose Matanuska, Lemon OG, Maracuya, and Amnesia since they grow better outdoor.
