well from what i could see from online specs it seems to be ok (but not the best) on nutes but what ph is the soil at? i herd from a little birdy that it ph's in the mid 6's which is not ideal but not tragic either. you could always use something to raise (or lower) the ph if need be. so if by screw up you mean "killed the plant," then most likely not unless you slapped it around a little before you planted it. just look for signs of stress like wilted leaves and browning. remember by planting it you most likely shocked it so it is not going to be jim dandy right away but give her some time and see what she does. IMHO she is not going to just kill over.
