I don't really use nutes... so my experience is limited, but it looks like you're still in or just starting to finish pre-flower... which means that the plant is really just starting to want the bloom nutes. A little nute burn is ok... if it was me doing your grow, I would probably skip one feeding... maybe two... just add water, then go back to you're regular schedule.
Weeks 1 through 3 in flower using want more P nutes then N or K
After week 3 in flower, it's more K, little less P and next to none N
Happy Growing!š
