I have 2 Red Savinas I'm growing, that I bought through chileplants.com. Let me state that I have never grown anything plant-like before, so I don't know squat. I'm growing them in pots, as I do not have the space to put the them in the ground. I put them in the pots on April 21st. They started out at about the same size. But after 28 days, they do NOT look the same anymore. One is tall, green, budding and strong. The other seems to have stop growing(no new leaves or buds), and is a slightly yellow color. I have watered and fertilized them the same. I fertilized them with seaweed emulsion when they first went into the pots. Since then I have fertilized them twice with fish emulsion.
So my question, what can i do to get the sickly Red Savina back on track?
Here is a picture of them together :
Thanks for any information/assistance!!
