oh, Ca(Calcium) deficiency can also show up as stunted, crippled growth.

I've never been able to induce Ca++ stunting in aquatic plants by witholding Ca from dosing, but I've not tried to really limit it and use RO with less than 1-2ppm of Ca++ to see either.

I think it's exceedingly rare, but very often blamed, CO2 is very common and dose the same type of stunting.

Been there and done this many times.

Sorry,

Been busy writing my dissertation......have to defend in a couple months. I have been taking photos along the way however (except the last two weeks) and will post them at some point. I am actually going to start the nutrient limitation again to see if I can turn the plants back to red.

how's the plant going?
have you been able to turn the plants back to red?

I am really curious about the conclusions of this wonderful discussion.

I have heard about limiting NO3 and PO4 may make the plants get redder.
On some terrestrial plants, higher light may induce some hormones that turns the leaf into red, is this applicable to aquatic plants as well? some folks say so...

My experience is by limiting NO3 may increase the variegated color of my anubias, but doesn't guarantee the red coloration (which can be caused by many other parameters for sure).

For certain, having lush and healthy plants (showing their real color) is one's great joy.
