Hi weedawan. I personally never let automatics sit in small pots, because they dont like it at all and may stay small. But we will see.I put them always in their final pots filled with a nice soilmix ( as you have=) those greenhouse feedings ar very strong, and i know different persons who overnuked the plants with that stuff. I whish you maximum succes for your grow. I recommend you the Green Buzz Liquids line, its a great organic liquid fertiliser line, filled with beneficals. here in GD is a Representant of this Company. Just hit
