Can anyone here tell me the scientific term for a plant turning red under bright light, my investigations led me to learn a new term but not the term I’m looking for, the new term is “heliotropism” what a word! It’s where a plant bends toward the sun.

I haven't found a neat - as in one word -term for it yet.
The closest I've got is : 'anthrocyanin biosynthesis' ; 'anthrocyanin synthesis' ; or 'foliar anthrocyanin biosynthesis'.
Anthrocyanin is the red pigment which (I've just read!) masks the green of chlorophyll, thus making photosynthesis tougher for red-leaved plants. Opionions seem to differ on its purpose : uV protection ; anti-oxidant to help protect against fungi ; protection from visible light (don't understand that one!) ; nutrient deficiency ; and osmotic adjustment for frost protection are some of the things that I saw mentions of (talking about terrestrial plants).
I'll have another go looking for underwater plants and come back if I find anything of interest.

This now completely off-topic but thought I'd put it here since it came up in my second attempt to answer your question!
It references a study on the effect of "high" nitrate on Vallisneria asiatica. By "high" it means 10mg/l ! No stress effects, such as reduced photosynthesis and inhibited nutrient-uptake were found at 5mg/l nitrate but when they cranked it up to 10mg/l the plants suffered to some extent from such things.
I wonder if that happens in other underwater plants too.
And I didn't find a one-word answer after all !

That was my first thought, too! Then I re-read the brief and saw licence for me to go OTT!
