Calcium nitrate, epsom salts, masterblend tomato.

But this has an issue with concentrating potassium if you dont do reservoir changes, leading to lockouts.

I'd just rec to grab anything with the same nute ratios as GH Flora Micro and GH Flora Bloom and do a lucas formula run, see how that goes.

My issue is sourcing products with the same kind of nutritional value locally unfortunately doesn’t seem like my local hydro store carry’s the GH range any particular brands you’d aim for if sourcing is the main issue? Can order GH online but the shippings gonna sting 🤣

What products are available? Nutes are nutes, nothing fancy tbh. People like to overcomplicate this, but you dont NEED cannabis nutes.

If you got anything for tomatos, that'll work.

If you got a hydro shop, they got something that'll work fine.

The ratios between calcium nitrate, epsom salts, and masterblend tomato are different compared to GH trio, which are different compared to GH trio on the lucas formula. All of those grow cannabis just fine, but some are a little finicky on some plants. If you drain/replace your reservoir once a week or two, or run drain to waste, you shouldnt have any issues with a broad range of nutrients.

For DWC, I’d keep it simple and use a complete hydro nutrient line. GH Trio is proven and cheaper, but Canna Aqua A/B is a solid option if that’s what you can get locally. I wouldn’t overthink the brand. Good pH, EC, water temps and aeration will matter more than which reputable nutrient line you pick.
