Hello, I'm running a new set up and I've noticed glassy patches and yellowing tips on my rotalla green and on my downoi, I'm dosing EI and my co2 is super high so I'm assuming I shouldn't be deficient be anything. I checked james guide but it doesn't seem to fit anything. Any one have any ideas?
My tank specs are:
60x30x30
1x 24w t5 for 6 hours
co2 via Fe 2 hours before lights goes off at the same time as the lights. Drop checker is on the yellow side of lime when lights come on and yellow when off.
substrate is ada amazonia
dosing is full ei since last wednesday.

Have the leaves only turned yellow since you started dosing EI? Maybe the balance is'nt quite right with regards to the ferts, the amount of Co2, and the lighting. Although from you're measurements you've got about 2wpg. Maybe with the amount of Co2 you're injecting you need to up the lighting?

I've always was dosing half ei then when I received all of my plants I upped to full ei. the tips of all the rotallas are really yellowy acid green and lower down the tips of the leaves look burnt/black/brown and sickly looking. The rotalla could de desribed as leggy I guess, there's about an inch between each leaf node?

I assume it was a pot that TGM had already grown on, it was a little tatty to start with but there was loads of it so I wasn't too bothered. I didn't notice the deficiencies until I did a major hack back and expected lovely fresh growth that didn't come. Here's the look i'm going for http://i405.photobucket.com/albums/pp13 ... rune_5.jpg
but mine looks ratty and limp.
And yeah, an inch between the nodes very thin stems too except when I took tops and replanted them.

Yeah, I left it to grown up to the surface then spread about 4-5 inches or so forward it wasn't that many stems that got so long, about 8 at the most.
I've always been brutal with my green and never found it an issue until now, it's been one of my most resilient plants which makes me so confused as to why it's gone so ratty now.

Oh, I forgot to add, I'm also dosing easycarbo. I'm thinking about double dosing Ei and seeing where that leads but I should already have ample ferts?

Upped the trace dosing and added a second tube, fingers crossed that should sort things. I've kept re-reading James' site and I'm pretty confident it's a trace issue.

Symptoms look like low CO2 so if the injection rate is high, dropchecker fluids are normal and Easy carbo is being dosed the only thing left is flow. EI plus AS ought to have all the bases covered from a nutrient standpoint. This points to flow as well.

Cheers,

Flow shouldn't be any issue i can see the stems swaying and the turnover is 1200lph on a 52l tank. :rolleyes: :bored:
