Q. 3) See prior question 1242. What happens if one of the sheva brochos was said with mistakes that change its meaning, such as instead of Shehakol Barah Likvodo in the first brocho, one said Shehakol Nichye Bidvaro or Yotzer Haadama instead of Yotzer Haadam?

A. If instead of Shehakol Barah Likvodo on the (first) second brocho, one said Shehakol Nichye Bidvaro, it would seem obvious that one does not comply as it is a totally different brocho (Birchas Hassanim p. 227).
However Horav Shlomo Miller Shlit’a pointed out that this may depend on the pronunciation of the shehakol brocho. Magen Avraham (O.H. 167: 8) quotes two opinions as to the correct vocalization; Nihiyo (past tense) or Nihiye (present tense). Nihiya means “by whose word everything came to be” whereas Nihiye means “by whose word everything continues to be”. Beeir Heitev, Shaarei Teshuva (204: 20) and Biur Halocho (204: 13) all maintain that we should say Ninhye since that is what most people say.The prevalent practice is that Ashkenazim say Nihye and Sephardim say Nihya.
The Rov maintains that if one said Nihya, it is possible that he complied with the brocho of Shehakol Barah Likvodo, also said in past tense.
As far as saying Yotzer Haadamah instead of Yotzer Haadam, Shevet Hakehuna (p, 129) rules
that it is clearly two different blessings, and if he didn’t fix it immediately (toch kdei divur), he has to repeat. Horav Shlomo Miller’s Shlit’a opinion is similar.
