it is my understanding that a 2 week old from seed should probably not be in a 5 gallon container. some ppl judge the size of container based on the width of the largest leaves, perhaps a 6" container by the look of the plant. also, most plants in soil that appears to be that rich should not require additional food so early. i'm sure other will chime in but that's my take on it. i am just starting some sharksbreath & saw this post. good luck with 'her'.
