Without more info I would say its very likely just from the temps.We were in the mid 80's a week ago. Then we had this late cold front just come through. It's been in the very low 50's at night and mid 60's during the day.

Then there may be a bit of an issue with nutrient uptake. Might be PH, might be temps, might be roots, Hard to say, when you change temps, humidity and light source it changes the rate of uptake and you may have to adjust your feed. If you can list all the parameters and info you can including issues that you had during the grow it may help to narrow it down. I can tell you its definitely not chronic overfeeding but don't take that as feed more. Really I think its more temp related and possibly PH or light nutrients but you need to fix the temp issues first.As far as the purpling, it's been like that before I moved it outside. I really pissed it off with training. It didn't like it at all. But all of the others are fine. I only moved them outside because I ran out of room for them in the veg rack. They will be going into my flower tent once those girls finish up in the next couple of weeks.

Looks like it could be nutrient burn and deficiency. Or that pattern looks like mites like you say.
Cant see much from the microscope pics but those spheres could be stalkless trichomes like i saw when i first thought i had a bug problem. Turned out to be too cold temps at the root zone.
I would at least blast them off with a hose or wipe the leaves with iso alcohol. Then keep an eye.
I would never bring plants that were outside in to my growrooms.
@Phylex In my humble opinion I get the impression your a good knowledgeable grower who knows there shit, you've given me some great food for thought and advice on here.
Normally my first thought would have been a ph issue but when it's you I know that ain't the problem. I'm inclined to agree with @Aqua Man , could well be the change in environment
I hear ya on bringing outside to inside. I couldn't agree more. It certainly wasn't my plan. I ended up waiting a few weeks longer than expected on my new LED grow lights and it threw the timing of everything all off. They just outgrew the rack. So it is what it is. A lesson learned. I've been worried about the thought they may get infested with bugs leading up to putting them outside knowing they would be out there for a couple of weeks. At least they won't contaminate other plants. They'll be going in the tent all by themselves. Worse case, they get infested and I have to treat them all anyway. Not to mention hoping I sterilize everything adequately enough before the following grow. Best case, the weather starts cooperating, they remain bug free, and some nice big plants get flipped to flower.
Looking at my weather app, the temps have dipped into the mid to upper 40's in the middle of the night. The root zone is definitely getting cold. But it's a pretty hardy plant. I'm sure they'll be fine. They may have some battle scars afterward, but I don't think it isn't anything they can't bounce back from.
Off topic, but you and I were discussing my taps ppm. I guesstimated 220-250 ppm from memory. My memory failed me. I tested it this morning and it was 186-188. I'd bet my memory on 220-250 was after I had added a small dose of cal/mag a couple of months back.
I'd lean more towards deficient and lack of nutrient uptake. I haven't hit these with any heavy dosages yet. I've also been a lot more focused on my flower tent lately.
i agree,im thinking stress from the move,a garbage bag over plant at night would help straw or pine neddles around base of pot too,i wouldnt take them back inside if you can grow outdoors,i have never seen any plant outdoors that dont have some type of bug,trick is keep them leaves shiny and most will be gone,you cant control them at all but neem oil is magic garden side if you dig,coming from t5 to direct light is a big thing and they will stress a little ,as your doing hardening off is the key,another thing them plants will explode with father sun and you will be impressed as soon as you sort things out,jmoWhen plants are started outside they are much hardier to the sunlight and cold nights. Maybe put a cover over them at night. I believe they call it a cloche (sp?).
And i would want to know what is in that tap water. It could be more than acceptable.
