what's happening to my crypts??​😱​

[Mengo]

I use root tabs and dose seachem flourish comprehensive. I can't seem to figure out what wrong.

Crypts are my only rooted plants and they all seem to have holes in their leaves. It's been like this for a few months now. They're growing slower than they usually do. New leaves also emerge with holes in them. What's causing this???

Most likely a nutritional issue, flourish complete doesn't contain nitrates which plants need in large quantities. Hence the yellowing, crypt also chew through root tabs in no time. 

As for the holes, it could be nutritional or caused by live stock.

i've got a pretty decent stocking though. nitrates are usually around 30-40 ppm and i do monthly water changes. 

i added a root tab a month ago but i'll add one more and see. 

I also thought livestock could be the issue, but new leaves also have holes.

Light is the gas pedal when it comes to nutrient uptake, another thought is your light might be too low
