The biggest one is starting its 5 node....but it is still very small..say 3 inches high and its span 3 1/2 inches across. Like i said the first one popped on 4/23. As of now 4 have that dark color to them and do not appear to be growing. I have another that is on its 3 node but that one is starting to darken also. Ok i know it is no a total waste of time but there is one big problem...im not sure what happened so how do i fix my mistake for next time?? ive done the reasearch and even had someone helping me that has 3 grow under the belt...i just dont know what went wrong....please help.
