I disagree. It could be one of those things..not sure about the fan.. but it could very well be Mg issue. Or many other things. The cold is certainly not the only thing that causes purplingThe purple coloration doesnt come from Cal or Mag deficiency, that plant looks healthy. It might just have a little cold. Maybe fan directly blowing on them ? Water temperature ? or Minimum temperature at night? Its surely one or the other.
Purple stem at the medium meet point can be a disease issue but your rockwool looks clean. What’s the roots look like? Is there any foul smell around the roots?Here is a few close ups:
I agree with ya there. Last time you said “it’s surely one or the other”. I agree if it’s a mag issue usually from some kind of lockout. I never supplement cal mag. Just saying it could be a lot of things not knowing much about his grow.Its rarely Mag issue if you have a good AB base.. If using RO water, add Cal-Mag. But its way more common to see variation in temperature than Mag Deficiency... If it was Mag problem, you would see on the leaves, but they seems green enought. Can be a phosporus problem tho but again, the leaves would turn a bit yellow. I would bet everything I have on temperature problem. Maybe too close to the AC. Epsom salt will hide the thing but wont fix the problem if its coming from environnement.

And considering they are from a dispensary...
Ya true. And I think you misunderstood a little. I wasn’t trying to imply that I thought it was a def or anything. I was just saying it could be multiple things and Epsom salt spray is a good way to eliminate the possibility without hurting the plant.I agree with you also. The thing is, if it was food problem, the new growth would be affected. They seems green as hell so Im not quite sure is a feeding problem. Is the hydro table directly on the floor or is it isolated from it ? The fact that only the bottom of the stem is turning purple is also a sign of cold because it has the tendency to drop at the bottom and stay there while hot air rise up if not enough air movement in the room.
Ya definitely healthy!
Well when I went to look at min/max meter... The max was 72.7 and 59% while the min was -40.0 and 0%. Currently sitting at 67.8 and 56%.You dont want the root to be under 18 degree celcius or 64 F or the stem will turn purple like that.
Ya didn’t know it was that cold. Hahah. 72 max with lights on means it’s probablh getting close to 60.Told ya it was cold hehe ^^ add a bit of heat at night and everything will be fixed.
My house never drops below 67 so I can't imagine my tent gets much cooler. And my lights are off from 2pm -8 pm(warmest time for house).Ya didn’t know it was that cold. Hahah. 72 max with lights on means it’s probablh getting close to 60.
Still could have been a lot of things. Hahahah
Ya that’s good then. Well yea if you raise the temps and it helps the purpling then we’re golden. Lol. The riots look healthy. Doesn’t seem that cold to make it go purple but we’ll see. Haha.My house never drops below 67 so I can't imagine my tent gets much cooler. And my lights are off from 2pm -8 pm(warmest time for house).
