Back right and left have these, and Half the plant is purple and the bottom half is green

Prolly nothing. But P not being absorbed. Do you have cold air blowing on them.

Some plants have a pretty rich reddish purple hue.

Several reasons this could be happening. One is a temp diff of 15 degrees or more will cause stem purpling. 2 A possible mag def. 3. Genetics. Dissolving a tablespoon of non scented epsom salt in a gallon of water and lightly spraying your leaves just before lights out will answer that question for you. Keep us posted!

What will the rosin spray answer?

Epsom **

Epsom **

If it’s a mag prob the epsom salt spray will right the purple stem allowing it to green up again. I mentioned three possibilities, the only way to know sometimes is to troubleshoot a bit. What is your temp variations?

Switch places with another plant. If that one changes, it has to do with cold air flow.

P-K and mag. just overall hungry is my guess. Increase feed a bit.

I would agree with the Epsom as I would be more concerned with the Mg def I see in at least one plant then the purple stem. Maybe you should include media and nutes you use.

What's the machine doing next to the worst looking plant in the top right corner? Machine could be the culprit.

you need to define the environment to get a better diagnosis. Temps (day -night), humidity (same), strain, floor (under the tent - is it cement, etc. - where is tent located), what you are feeding them and lastly the light (spectrum / distance, strength)
It will not hurt to spray with the epson salt mixture - 1 tsd per gal water, only at lights off or first thing lights on...If it is a mag issue, this will help in just a cpl days
Some strains, when the temps swing or are colder, will result in red / purple stems, leaves
Light too close can do this
Plants overall look very nice, do not overthink this...purple does not hurt
look at my GDP - a natural strain with heavy purple colors
