Severe déficiency on my s.repens :(

Is that CO2 defficiency (slow to no growth, younger leaves are very small, older are yellow white)?

Thanks

Hi CooKieS,

Looks like your S.repens has a stunning growth. If you doubt about CO2 deficiency, you might bring the drop checker lower to the place that S.repens are there. CO2 should be well distributed to all the corners of the tank. If it is low, then bring up CO2 level gradually. Dose some Seachem Trace/Flourish if you have not done so, too.

You might bring some S.repens in your tank and try to plant emersed, once it grow stronger, then harvest and put back to the tank. Propagate it with normal garden soil is fine, then cover the top with ClingWrap to keep the environment moist at all time. Spray water 1-2 times a day. And you can keep outdoor if has sunlight (no need to be direct sunlight).

My S.repens in emersed form in the photo.

Hope your S.repens can thrive back again!

Hi all,
You might want to check lighting again. I think it needs more lights
It might be light, but my suspicion is that it is magnesium (Mg) deficiency, mainly because I think you can see interveinal chlorosis on the new leaves.

I'd try some "Epsom salts" (MgSO4.7H20), and if that doesn't help, maybe some KNO3. Magnesium, nitrogen (N) and potassium (K) are all mobile within the plant, so if any of them are deficient you should get a really quick greening response.

cheers Darrel
 
Thanks all,

I think dw1305 is right...

Light is 3000lumens for 18cm height tank, more than enough. Also my elatine hydropiper, which is a high light plant, is growing nicely.

I'm now diffusing CO2 24/24 but only 0,5bps, so my drop checker is always light green (was on 7/24 before, so blueish drop checker at the beginning of lightning period)

I've also upped my daily dosing regime, including 0,4ml of aquarebell eisen (iron+micros...mg,ça etc)

Let's see what happens! :)
