Mg defiency, how much to dose?

MichaelJ said:
Unless you recently trimmed it down considerably, and considering this is a CO2 injected tank, I would have excepted way more growth from these plants after a year.

it's been trimmed countless times haha. this is after full replanting a week or two ago.

OK Good .. it kind of looks like it was planted week ago 🙂

Ok, that piece of info might be helpful for the experts... I might suggest that the plants are just adapting after being replanted and you just need to wait it out a bit. ... but checking into the CO2/flow situation never hurts.

Ha never seen that before. Can you see loads of CO2 bubbles at the substrate. Bubbles may all escape to the surface and not reaching the substrate

can see bubbles all the way around the tank. pointed downwards so it gets to the substrate well.

Just an observation from your journal My 12G softwater which I assume is the same tank? In the last 3~4 weeks you seem to have changed from a lily pipe on the left, to a spraybar and now with your current outlet setup, maybe this inconsistency is contributing to the problems you're having. BTW this is just me thinking out

not practicing what I preach. I see 🤣. I always say consistency is the key to healthy plants. I'll keep that in mind. thanks!

@plantnoobdude Definitely progress - Very nice! your Mg content must have been very low.

Edit: here is the post by @dw1305 re Mg content of NW Europe water: Magnesium content

Ok, your using pure RODI water so the above is not relevant for your situation, but still interesting for people using tap water and encounters a similar problems caused by Mg deficiency.

Cheers,
Michael

perhaps the demands of a high-tech tank were higher than I thought. After all magnesium is a secondary macro nutrient.
