Is this normal??

This is lights on for about an hour, note the "rusty" pigmentation.

This is 7 hours later, same camera, same settings. same ligting, note the total absence of the "rusty" pigmentation.

I have also observed this in Bacopa caroliniana in a tank with 55g, DIY CO2, and 1.75 wpg with a 96w PC from AH Supply. The plant would be deep pink in the mornings and turn lemon green in the afternoons right before the lights went off.

I tested for PO4 and NO3. I found my PO4 to be practically unmeasurable. My NO3 was 5 ppm.

I started dosing small amounts of PO4 in the mornings. I noticed that a few hours later, the Bacopa began to turn lemon green earlier in the day. I added more to the point of having 0.5 ppm. The Bacopa was no longer pink in the mornings (nor have such short internodes).

Just my experiences,

Carlos

Do you think that these changes of colour are deficiences related? or you think they are only minor changes in order to promote "pigment adaptation" to improve the individual success?. Thanks. Maurici.
