hey mate
yes, it could be a cal/mag def ...
u use led for lighting ?
depending of ur medium , if its in soil , yes you can start the feeding and add some cal/mag in the recipe

I wouldn't worry about the purpling. Alot of times it's genetics. It could also be from cooler temps at night? Either way they look healthy.
I would, however, be concerned, using river water. Hopefully you have a plan to filter it. I would think river water would be a great host for bugs.

It is tough to see in the pic with lights on but, I think I see a couple rust spots in first pic, after closer inspection. @LordGreenWood is correct. You will need extra Ca/Mg with LED.

yup , i see the rust spots too , and yes the purpling can result of genetics
maybe a ph issue ?

btw : i add cal/ mag when i start the feeding in the 15ish days ( with light mix soil )

I use the same medium. You definitely need Ca/Mg buddy. You got any?

Cold night temps will cause red leaves and stems as well... or so I heard...
