Weepy curly sad leaf syndrom?

Ok straight to the details:

Soil: FFOF
Strain: King Kush Auto
Age: 19 days since sprout
Nutes: None
Water Regime: About 1.5 x per week of 6.2-6.5 PH'd water
Pots: 3G Smart Pots
Lighting: 6x 50W Cree CXB3590
Environmental Variables: It has been very hot and humid. Specifically up to 72% RH and 89° in the tent.

The shiny spots aren't wet and they don't smear. When I rubbed them nothing moist or visible transferred to my finger that I could detect other than a nice strong smell. This particular plant was suffering from a lot of leaf taco-ing for about 2 weeks but oddly enough now some of the leave edges are curling up while the tips down. The leaf in this picture is the absolute worst one.

I've looked 3 separate times with a lighted 45x magnifying glass and don't see any signs of fungus or bugs under the leaf.

Frankly I'm just sad for this girl. I was thinking maybe it was in a hot-spot so I moved it the other day and nothing changed. I haven't applied any nutes. The very strange thing is I have 5 other plants and this is the only one that is weeping like this. A few of the others are somewhat droopy but nothing close to this. This one also happens to be the tallest.

Any thoughts? Thanks in advance!!!

Adding a shot of them all. The sad girl from which the photo in my original post was taken is the lower right plant. Ignore my ghetto thermostat gnat paper shade haha. Anyhow, see how everyone else seems to be happy joyous and free? Then there is King Kush over there looking like someone kicked its puppy.

Any ideas?

give it some time to see if the new growth has it or gets worse if it gets worse off it. An uncoated aspirin dissolved in a gallon of water is what tomato growers use to fight it it really helps to keep it from spreading to other plants.

Thanks for the reply! Today I woke up to this, it seems to be progressing and now killing the leaves. This is on fairly new growth mid-way up the plant, maybe 3rd node. With no diagnosis I'm half tempted to pull it out of the tent. I've got some old school uncoated aspirin so maybe I'll try that with a minor flush.

I'm hoping this new symptom maybe helps shed light for others to identify the problem, I'm still at a loss.

Ok I've pulled the plant and went with a 1G minor flush with 1 crushed uncoated aspirin dissolved in. She's setting next to a window now suspended above a 5G bucket to fully drain.

A little too hot as well as humid, maybe a little bit too much moisture either in the air or the medium, plus underfed and Mg def, looks like. Makes sense, given your heat, room humidity, and the fact they're over two weeks old and completely unfed. When they hit 21 days, feed them 1/4-1/2 strength, and give them sone kind of CalMag supplement. Turn down your heat at least 5 degrees and get the humidity dropped.

Will do and thanks a ton. Dehumidifier will be here Thursday and I'll dimm down the lights a tad and raise them a few inches. I'll wait till the dehumidifier has ran for a bit before putting her back into the tent. This heat spell is supposed to be over next week. Thanks again!

@Olive Drab Green - Ok today is day 22 and I've applied a full dose of calmag plus and 1/3 dose of FF grow big. PPM with water came out to 588. Dehumidifier is killing it, keeping things right below 60% and since dimming and raising the lights slightly, I've been able to ensure that peak temp is 83°.

@backtracker - Did the crushed aspirin on the suffering plant. She's out of the tent for now but new growth looks very healthy. She was also given the same as the rest (above).

Hey gents, so the plant is still quarantined and growing however the symptoms haven't subsided. Last night I pulled a leaf for some super close inspection and this time I was able to make out what seemed like tiny bubbles or blisters. I couldn't see anything crawling and these bubbles only appear on the underside of the midrib. Given the intense glossy appearance on the leaves I'm thinking maybe some type of mite? Broad/Russet mites cause shiny leaves but on photos that I've looked at, you can actually see bugs. I can't see anything, just the aftermath and now these tiny bubbles.
