That is the topic of my discussion here Theories on proper NPK cannabis ratios - #19 by Worcestershire_Farms
Honestly, I fuss with my African Violets. They have a soilless mix so they need water supervision, if the light isn’t perfect they don’t bloom and they need feeding with every watering. If you get it right, they are instant gratification and continuously pop out flowers. I love them! Everything else, LITFA. lol
