Staurogyne repens deficiency help



Anyone able to help identify this deficiency I'm new to this high tech tank stuff, my dosing regime is

Sunday - 50% water change
Flourish 2ml
Seachem phosphorus - 8ml

Monday - iron 1.5ml
Potassium - 5ml

Tuesday - iron 1.5ml
Flourish trace - 5ml

Wednesday - phosphorus - 8ml
Potassium - 5ml

Thursday - flourish 2ml
Phosphorus 8ml

Friday - iron 1.5ml
Potassium 5ml

Saturday - phosphorus 8ml
Flourish trace 2.5ml

I don't dose no3 because my nitrates always test between 20-40ppm but am curious of a bad test kit. But it is well stocked.

Co2 drop checker shows a yellow green at 4-5bps in a 20g, all my ferts are based on Seachem liquid ferts

It's a micro-tox.

I would cut out on the trace nutrients (iron, trace, flourish) and only dose macros, NPK. Also, take a good look at the condition of the plants. Notice the twisted leaves, how algae smothers them, and the lower leaves falling off. If you see this, this is a sure sign of trace toxicity.

If you are driving off a cliff at 100mph, do you think slowing down to 50mph will prevent driving off?

It's unlikely you'll need K2SO4 since there's more than enough K in KNO3. I think there are links to how much a dose will provide in the plant section.

It makes sense of toxicity, since I bought iron and trace my repens started doing this, before it grew nice lush and green

Could this be causing increased gda?

Yes, excess traces can result in GDA, but probably indirectly by providing nutrients for the bacteria that the algae has a symbiotic relationship with.

I had some of that stuff flourishing great then one day it al started to look like it was eaten up falling apart thought it was all going to die. Then I read somewhere that it does that and bounces back so I rode it out left it alone and it actually did bounce back after awhile better than before on its own.
