Bloom booster recommendations for RDWC lucas run?

Hey all.
I'm approaching week 4 of flower. Running RDWC under a bit under 400 watts of light. Been feeding her based on the Lucas formula and I was wondering if anyone had any suggestions for a bloom booster? Not looking for anything extreme in terms of NPK ratio and I'd like it to work with minimal adjustment to my current feed ratios. Anyone have good experience with a particular product while running lucas?

i always thought lucas by itself was good.

i do use silica for the entire grow with lucas.

i was playing around with fulvic acid in the res last grow but it made my pH go haywire. i use it as a foliar spray now up until buds form.

I've also been running silica for this grow. I actually alternate calmag and silica every other res change. Seems to be working out. Was just curious if anybody found any benefit to adding something like liquid kool bloom or something similar. Ultimately I'm ok with sticking to straight lucas if nobody thinks I need anything extra.. she's looking pretty good so far..

Was just looking at some bloom boosters myself even though I have 8 pounds or so of mono-potassium phosphate on hand. I run dynagro foliage and a silica additive and then add the mono-potassium phosphate at flip.
I taper off the dynagro foliage pro but when I do that I also taper the micros that foliage pro contains.
I was supplementing micros with flying skull elite micro but that's not real easy to find locally so I've been looking for something else and today I ran across a product called Flower Fuel. I ordered 2 250ml jars today, couldn't seem to find any larger containers.It's gotten some good reviews and contains micros and l-amino acids. My order hasn't been shipped yet but I'm anxious to give it a go.
Not sure how it would work with your feed schedule.

Thanks for the info! Appreciate it!
