Whats wrong with sword leaves?

[Fishies86]

Hi, I was hoping that someone would be able to tell me what's wrong with my swords leaves. Just on one of them, the new leaves are coming through all buckled and blistered. They are also a reddish brown colour.
I have got root tabs in the substrate (fine gravel). My lighting is two 15w bulbs, 6000k each. I don't have co2 yet, but am planning on trying it soon. My water test results are :
pH- 7.6
Am- 0
Ni- 0
Na- between 0 and 5.

I tried feeding a liquid feed as the nitrAte is low, but my Vallisneria tend to melt. Any suggestions with that too?

Sorry about the pic quality, taken with an iPhone.

Thanks in advance!

Tank size?

 

[Fishies86]

Oh yeah, sorry. It's 48 litres. About 12 and a half us gallons I think? It's about a foot cubed I forgot to attach the photo too, and while uploading it my phone battery ran out, so still trying to upload a photo

Do you have any fert by the roots? I had an issue like that in the past

Yeah he has root tabs, but I don't believe you have enough light, swords are a medium light plant if i'm correct.

Lol it was Submerse when I got it and has been since. It was a baby that I pulled off a mummy plant that I bought. It had 2 leaves at the time and thrived when I separated the two, but it's recently started growing weird new leaves. I've been trying to upload a pic but keep getting a message about a 'parse error'

I keep getting that error too.

Finally! I downloaded the update and now I can post pics. Tadaa! I know it's not great, but it's the best I can get with my phone.

That looks like a deficiency to me. With your low nitrates I think the plant is lacking both nitrates and potassium. I would consider adding a liquid fert, ferts should not melt plants, vals would be effected by Excel which is a carbon supplement not a fert.

Oh ok that's cool are there any good liquid ferts that you would recommend? They have to be available online or via eBay as I live in the uk. The only one I've been able to get hold of is pretty rubbish. It doesn't even tell you what's in it. Just says 'trace elements'.

Flourish comprehensive is a great liquid fert

Excel comprehensive is a great liquid fert

Didn't rich say that excel would melt my vallis? Or is that different?

That is different Floruish comprehensive is a fert, Excel is the CO2 supplement that will melt some types of plants. They are all made by the same company.

Flourish? Ok I'll try to get hold of some of that thanks guys
