keep in mind this guy has a pool full of goldfishI gotta go but I would dump about
2 gallons of water in the soil.
Just to be safe. If that is fresh soil it probably already had food in it.
I have not used those products so im just guessing..
If no one else chimes in soon.
Flush the soil and let it dry and dont feed it again until you see the lower leafs
start getting light green or yellow.
