Hi one of the 3 plant (same strain) leave stem is very purple looking. Is this due to deficiency? There was strong winds few days ago, can this be stress? Current ph is at 6.2 in soiless medium. Should I increase ph for mag to absorb easier? Please advise and thank you in advance

Could be a P deficiency, but could be genetics too. Raising P is dangerous. If ~50-60ppm, don't go higher. Assume it is genetics. Otherwise, you will likely lockout numerous other necessary elements. LED lights are notorious for this. If all other things are fine, I wouldn't worry.

My plants have the same color looking stems for some of their fan leaves, not too worried about it as the rest of the plants seem to be doing fine. As long as the rest of your plants aren't showing any signs of deficiencies, I wouldn't worry too much
