Bio bizz light mix
Water ph 7.0
22 degrees c
Biobizz Nutes (grow and fish mix for now)
Led lighting (600w draw)

I’m thinking iron/mag ? But need advice

You're short on Mg and perhaps N as well. For sure though Mg...Epsom salts is your friend.

I thought this but many people say if the water isn’t RO then don’t bother with salts/calmag as the water is sufficient

But your plants are telling you something different....people will say this or that, charts will suggest this or that, but the only one true way to know for sure is to listen to your plants. However, you're the grower so do as you see fit. Good luck.

Bring your waters PH down to 6.3 with a little citric acid ... soil or not ... and watch what happens.
You could try half strength calmag too. Not all water has sufficient amounts. Check your nutes to see how much they provide, if any.

I will try that thank you, I read about the citric acid when searching for an organic soloution to ph up/down. I consulted my water supplier (in the uk) and my tap water is moderately hard, wouldn’t calmag be harmful to the microherd ?

What's the numbers?

67.8mg/l calcium. It won’t let me copy and paste from the page for some reason. Is their another specific number you need ?
