Leaves drooping 2 days after water

the leaves on all of my plants are drooping bad. Just watered 2 days ago after pots were completely dry, they don't feel as dry as before now but appear to be wanting water. The droop started within 1 day of watering. I'm new to coco and not really familiar with how often to water. Pots are completely full of roots, last watering was 2 gallons a plain RO water ph at 6.3 per pot. I just turned the co2 generator on the last time I watered. Any advice is appreciated

P.s. The last picture of the smallest plant has been overwatered and has not received any water in 10+ days and it looks the best out of all of them.

Room temp day: 77-79 degrees
Room temp night: 72-74 degrees
RH; 50%
Water ph: always 6.1-6.3
Co2: 1000-1200ppm
Pots: 15 gallon eco pots cloth
100% coco

don't let coco dry out like soil, water it every day, or at least every other day. coco holds a lot more oxygen than soil, and watering it draws more oxygen in as the water passes through it.
it also absorbs calcium and to a lesser extent magnesium till it builds up to a certain point, so once you put enough into it you can back off on cal-mag. i like to add about 1/2 tsp per gallon of pot size of pelletized lime, have to use a lot less cal mag if you do.
you need to get a little run off each time you water, about 10% is fine, you aren't flushing, you're just making sure the salts aren't building up in the bottom of your pot
can't see if you have in your pics, but its a good idea to add some perlite to your coco, about 25% seems to be a good amount, makes it even airier and drains better
 
So you guys think they need water? I noticed the drooping about 12 hour after I watered with 2 gallons per pot. I use a sprayer wand to water the pots which waters the pots pretty evenly, i get good run off from around the entire pot. With 2 gallons I get a pretty good run off probably in the 10-15% range.
 
i don't think they need water right this minute, i'd give them time to perk up, then tomorrow water them with half as much, and start doing it daily, it might not run through the first day or two but it will eventually.
some people feed every day, i like to use a 4 day cycle, water, feed, water, cal-mag. i repeat that till they get to maybe the second week of flower then i cut out the cal mag, and feed every other time, but lighter

They look overwatered. I'd wait at least 3-5 days between each watering. 2 gallons per pot is also too much water.

That's what I was thinking, they looked overwatered but it happens so fast after watering I wasn't quite sure what to think. The pots feel light but I have definetly got them lighter between watering. I just flipped them to 12/12 2 weeks ago so I wasn't sure if they were wanted more water. Also some of the leafs feel dry and brittle.
 
plants use a kind of suction through respiration to draw water in, along with cellular absorption.
if the plant is a little too dry and you water it heavy, it drinks too fast and gets heavy, saggy.
gotta give it time to metabolize some of it, could hurry it by slightly raising temps and airflow
 
Also there is perlite in the coco, whatever comes from the factory though. Doesn't look like anything over 10%. I used the botanicare coco blocks that you expand with water, you guys might be familiar wih those.

I was thinking that could be a problem, I have good air flow but recently dropped my RH from 60-65% to 45-50%. Also the temps dropped from 80-81 degrees to 77-79 degrees when I turned on the co2 generator and fired up my second air conditioner.
 
i'm not an expert at c02 use, but what i've read says it works better if you have higher rh and temp, like 75%+ rh and 85F-90F? i may be wrong, like i said, not my field of expertise,
 
My best experience with co2 is 80 degrees and still under 50% RH. I've always done hydro so I'm not really experienced with hand watering plants, just changing reservoirs lol.
 
How can you over water coco in smart pots? Coco Has to stay wet all the time. I'm no where near even amateur growing but..... also 6.3ph isn't that a little high unless you have mag dif???

That's why I came here to ask questions, this is my first time doing coco. I run my ph from 6.0 to 6.3. I did 6.3 on my last water because it was just straight water and was close enough in my book. When I give nutrients I try to get my water at 6.0. No clue how I overwatered lol.... I thought coco was suppose to use tons of water lol.
 
fwiw in coco I shoot for 5.8 but I let it fluctuate between 5.6 and 6.1. Unless I see a cal-mag issue, then I feed emm at 6.2'ish for a day or so. But I try and stay close to 5.8. ;)

In flowering mine get auto watered every 4-6 hours depending on the size of the pots they're in, humidity, temps yada yada. However my mix is around 30%-35% perlite. Coco likes to be wet, it's not soil, but keeping a 100% coco mix wet all the time can be problematic so perlite to the rescue lol. :bigjoint:

How much water do you give Them at a time and do you think 2 gallons is too much at one time and how frequently do you think I should water them by hand?
