I'm pretty sure when your transplanting not to feed any nutes? Could be wrong, but I think so....but the plant does take a few days to get used to growing in new dirt,probably had a little stress while transplanting, it will bounce back..you have a nice drainage right? As for the yellow leaves, honestly I'm not sure, I'm not that experienced to give someone an answer...
But I do know never start off following the instructions for feeding on bottles , cut it way back to like 1/4 of what it says, introduce it
