You are also missing the point of TA on the Blossom Build, you are consuming the echos it provides with Spiritbloom which is correct in an echo build but not for a Blossom build. In the blossom build you consume TA echos with living flame or reversion to generate essence bursts for more blossom casts. You do this before a large spike of damage where you want to dump blossoms. You also sent R1 spiritbloom on yourself, where you can be casting at R4 for additional flames from Afterimage. Your emerald blossom casts seem low. 22 over a 5 minute fight isnt super, and you should be weaving offensive chronoflames between blossoms to take advantage of ancient flame in the class tree which you are also missing. this greatly increases essence burst generation and will help with mana in the long term.
