It's normal since she turn back from lvl70 to lvl1 and don't get doubled affection bonus like when she get evolved form.
Someone (I gess it's Roentgen) said some stuff about that some pages ago. Fesh bloomed form is weak compared to max level evolved girl and need a lot of ressources to back to their usual power. That's why 2nd affection gauge help a lot. And, IMO, why you should not bloom a girl until you have enough gold/manyu to quick level up her to lvl 30/40.
