Lucus Formula or 3-2-1 GH flora

Title says it all. Getting ready to buy nutes for my upcoming flowering. Have always used GH flora 1-2-3 G-M-B for flowering but debating using lucas formula which is 0-1-2 and keeping my PPM's around the same. I am growing in half Sunshine #4 half Ocean Forest with distilled water. Whats everyone's opinion?

Sunshine #4 half Ocean Forest bad medium sorry cant help ya ;(

IMO you really can't go wrong with 1-2-3, and 3-2-1 for veg. I started with this more than 2 decades ago. When the lucas formula first hit the web, i tried it, it's ok too. What I don't like is lucas in veg. Never have. Currently, in flower, i use a formula similar to the heads modified + a little grow, and plus a little cal-mag. But thats me in coco, with very soft water.
Hey, you should do a side by side, to see if ones better for you than the other.

Btw, I've done the 1-2-3 many times in peat based mixes. It works killer. I honestly can't remember if i've ever tried lucas in peat based(probably have). I don't see why it wouldn't work good to though
