Gotcha, thanks! I’m not using anything besides the standard API kit for measuring water parameters. Also have an old water meter that tests temp, ppm and ec, but it needs calibration, so I don’t rely too much on that. I’m just going off the look of the plants for the deficiencies. With no fish, any harm just treating it like a hydroponic setup for now? Within reason of course. I can always do a massive water change when it gets cycled, to remove or dilute anything bad in the water. Thinking to add jackpot micronutrient mix, as it looks like that should fix most of my deficiencies.

Whatever you add to your system needs to be fish friendly and I’m not sure any hydro mixes are but I may be wrong. I frequently am.
Regardless of whether you change out your water there will still be trace in the gbs. Just look at what a bit of galvanised roof run off can do to the fish in a system.
I still add blood and bone to my gbs to supplement but what you need is a slow and steady increase of trace elements and as tempting as it may be it’s a patience game ultimately you want to be able to add your fish and be confident your system can handle the bio load. The last thing you want is to add to the ‘Help my fish died’ threads.;)
Patience is a virtue.

I'm conflicted which plants to put into each system (NFT and grow beds). I have strawberries and leafy greens like kale and swiss chard. I have the strawberries in the NFT now, and greens in grow beds, but I think that maybe backwards just because of the root systems on each. The greens could have some height restrictions on the NFT, so I may need to re mount them to allow more height. Any recommendations on which are better where? Or am I overthinking this?

Probably overthinking it.

Just give it a go and see what happens.

I find root systems don't go as deep in beds as you would think, but tend to spread horizontally more.
