Anybody know why they look like this?

[TreeFiddy350]

so last week I forgot to water (dumb I know). So after the second day of drooping, I realized what was wrong and I watered them a little bit then they went to sleep (lights off). They perked back up again when lights came on. 2 days later they drooped again. I figured since 1000w is hitting them, they are drying out quicker, so I watered a more (both watering equaled about a normal watering). After I watered last night, they were perked up again around 2am. I checked this morning, now 9am, and they’re drooped again.
Could this be because of them being tired?(light turn off in a little less than 2 hours). Also, I noticed some leaves with weird shit on them. Can anybody help identify what’s going on and what needs to be done next?

what medium are you growing in? what are the temps, and rh?
what light schedule are you using?
a lot of plants will droop shortly before the lights go out, they're pretty much "tired" and can't process any more light till they get a break.
not sure that's all of this, but pretty sure it's a partial answer

You're drowning them.

Temps- 63-81 F
Rh- 40-60%
Medium- mix of FFOF,FFHF, FFLW
Light schedule- 18-6.
I wasn’t sure if they were being underwatered since I was kinda behind on last week schedule and did a small watering when I figured it out, then a small watering 2 days later (last night).
As far as those spots on leaves? What do you think that is? Could it be from the leaves touching the soil?

Why do you say that? Wouldn’t it be possible that they have been under watered? 7 week old veg under 1000w mh.
In 5 Gal smart pots

that is what it looks like ^

It's simple: lift it. If it's heavy, it doesn't need water. If it's light, it does.

It looks like you're simply over watering them.

no....it's not possible they are underwatered.
there are distinct appearances to different conditions.
underwatering is limp floppy leaves with drooping stems and petioles as well as leaves.
overwatering is tight, full leaves with a downward curl, and stiff stems/petioles......look at those plants and tell me which applies

They kinda look limp and weak and shit. I was thinking it might possibly be over watering and watering if when the lights go off if that’ll help them perk back up once they wake up.
Anybody know what those spots on the plant are? The first pic is from a lower leaf, which is why I thought maybe it could be from touching the soil about a week ago for LST

 

[Roger A. Shrubber]

i wouldn't worry just a whole lot about the spots, they don't look like insect damage, and there's no way to control whats going on until you get it dried out and start watering properly. overwatering can cause many different problems, root rot, fungus gnats, and lockouts of a few nutes, which can lead to further problems. get your roots in good shape, then worry about little spots, which will probably correct themselves...

So for now, should I just wait a few days and see what they do and wait about 3-4 days to water again?
I figure I will need some days of not doing anytbing so they can get back to normal, but then again, this is the first thing I’ve ever grown, so I’m kinda lost

yeah. at first, stick your WHOLE index finger into the soil, about halfway between the side of the pot and your plants stem, if you feel ANY moisture, wait till you don't....then water again. before you water, pick the pot up and feel how much it weighs, after using your finger 2 or 3 times, you should be able to tell by weight. you don't want it to start wilting, but you want it to be just a few hours away from it. that gives the roots time to dry a little, get some oxygen, spread out a little.

I don't know why so many who already own expensive testing devices don't get a cheap soil moisture gauge. I grow outdoor and the water needs fluctuate wildly according to weather and the state of growth the plant is in. If I watered each time my finger came out dry to my second knuckle I'd drown my plants in a week. Yes my soil is well draining, perlite enhanced. The action is happening down at root level and the meter reaches down there. The moisture level at the roots is what tells me when and how much to water, not in the top soil. No stab intended Rog, the finger measure is entrenched old school basic but the roots need air too and they won't get it if they are constantly drenched. I think a couple of wet/dry cycles will straighten out TreeFiddy350's grow. Yes things dry fast here in SoCal, but I'm near the ocean which ameliorates the desert climb with cooler moister air than in the desert or valley. Remember the old adage, "feed the soil not the plant", well I say feed the roots not the soil and let them breathe! Then give them a long drink and repeat.

not trying to be disrespectful....but those gauges are for those who can't develop the skill required to operate without one......i wouldn't get rid of my ph pen, because i can't pick up a bucket of water and tell what ph it is....i wouldn't get rid of my ppm pen, because i can't feel how heavy a bucket of nutes are and tell how strong it is....i CAN pick up a pot and tell if it needs watering or not, and it didn't take me years to develop the skill, it took about two weeks.....
as far as the finger thing goes, it's a temporary thing i recommend till you learn a better way. and the old school wisdom is the second knuckle, i tell them the whole damn finger, make sure it's dry....

Dude....

You said your RH is between 40-60 but in your pics its showing at 27, low at 23 and high at 57.

Okay, this is what's happening to your plant.

At lights off your humidity rises to the 50's...they start to breath again hence it's perking up in the morning...until....

your humidity drop again into the 20's....at this point, the plants are forced to closed their stomata to prevent rapid loss of water (vegetating plants cannot survive at this low humidity) hence there's no transpiration going on or no water movement within the plant and no water movement, your plant lose turgor pressure...…..hence the dropping during lights on.

Find a way to up your humidity...at least close to the 50's

See too about VPD, the relationship of temperature and humidity.

Hope this helps

I figured that the rh is wrong on the meter since it doesn’t seem to be able to get very high rh in a 4x4 grow tent. I use a 80$ humidifier that supposed to make the whole house humid af, but with the wattage on the lights going to 100, the rh seems to drop low, but whenever it’s 600-750, the rh tends to rise. Wouldn’t a humidifier be able to easily make a 4x4ft grow tent in the ranges?

Okay, you have a humidifier....that's good.

But first...if you're in doubt with your meter RH then please don't make up any number as to what you think is the RH....it doesn't help people who are trying to help you (that's why you're getting all kind of advice). If in doubt, get another hygrometer (it's not that expensive) to confirm your meter reading.

Having said that, IMO, I think you're meter is working fine and nothing wrong with it. Why I said that? Look at your temperature....you have a really wild swing of temperature there (63F-81F).

I gather that 63F is at lights off and humidity rises to 50's and 81F is full light on and humidity drops to the 20's. As you can see from that, there's a relationship between temperature and humidity.

Is your humidifier outside the tent? If so, put that inside the tent and have it running during lights on and turn it off on lights off. The other way....

Maybe you need a stronger exhaust fan to dissipate some of those heat (and also to pull out the dry air) and bring in fresh air with higher humidity percentage.

Curious though...where's that 63F coming from? Outdoor temp? Where's your tent situated...in the garage?

He's had the tent open messing with the plants. That lets all the humidity from evaporation out instantly. I wouldn't read too much into it.

Really...from 40 to 27.....just wow
