Your doinf fine, sometimesbthey start slow. I had a few start very slow. They grww the first leaves and stopped for a couple weeks before i saw anything else.
I just recently had one come up with the shell on. I got it off and there was this clearish white colored thing still on it. I guess it was like the inner part of the shell or something, i got it off no problem. Its doing fine now
Welcone to the farm. If that clone is from a flowering plant, its going to take a while before it goes into re veg. That could be why its not getting any taller
I never caught a carp either. Only catfish, sunnies, bass, trout around here. If your lucky maybe a musky, or a pike..never caught one of those 2 either
