With regret I may have to leave the Kessil club. I may end up selling my A350w's and try something different

Today I was looking back on my pictures of my tank over the pasts year and a half and realized I've had almost no growth. Not one new LPS growth (but no deaths), leathers are about the same size, xenia have grown a little, GSP is dying off, toadstool hasn't hasn't opened since I bought it several months ago, lost the little sps I did have, polys/zoas have multiplied a little, I've lost 4 anemones, no loss in fish, and my torch finally split for the first time after having it a year.
Water parameters are always within normal range for a mixed tank and I have good flow. I've always run an ULN but a couple months ago I started to feed a variety of foods a couple times of day to my fish it make the water a little more nutrient rich. Unfortunately nothing has changed.
My favorite LFS has ATI and Radion pro's on display (they also offer Kessil but have none on display and don't sell many) and colors were popping. They corals I bought from them looked way better with their lighting.
I ran MH for and CF's for years and had great growth. I thought about adding T5's to the Kessil but my tank is topless and I don't know how I would add them and keep things looking classy.
I've never had just T5 and may give a 4 or 6 bulb a try. The Radion's are nice but I'm just running a softie tank and don't want to spend $1500 on a pair of lights.
I know a lot of people love their Kessil's and I feel like I'm missing something? Any words of wisdom or experience?
Happy reefing
