It looks like you need a little more nitrogen but the real question is, why? If your ph levels are WAY out of whack then your new girl can't take much in. My guess is that you just don't have enough nitrogen in the water. Yellowing can also be a sign of potassium deficiency but its unlikely in this case. What and how much are you feeding them? What are the water temperatures exactly? If they're too high you would have problems as well.

Sorry, 1ml per litre it says above. I wasn't paying attention again...god I'm stoned... Anyway, one ml per litre probably isn't enough. But the good news is you can fix that easily. Better too little than too much. But do keep an eye on those water temps. You'll be growing more than grass if you aren't careful.

Oh, and if you decide to give more nutrition, keep in mind that it probably doesn't need a LOT more. So my advice is to take baby steps.

thanks for the advice, i heard that urine is a good nutrient for nitrogen, should I put some?
