I need some help diagnosing these please.

[Mrdudeman]

I'm working these 12 Night Nurse Mothers under a Gavita 1700e in 5Gal cloth pots in coco & pearlite 50/50 mix, temp runs about 82-87 with humidity within 40-55%, these were watered yesterday at a ph of 6.0 (about 18 hours ago) from a very thirsty state during their dark hours (18 on, 6 off), and I'm having one hell of a time getting them to cooperate.

This is my very first grow, very first time even touching this plant, very first everything. I'm growing both indoor and outdoor, outdoor is growing fabulous (Cotton Belt Soil).
But indoor is giving me hell pretty much non-stop. From pests to heating issues, to strains acting very differently, even watering problems. Due to many reasons, throwing out and restarting is not an option right now. I'm about stressed to tears and need some big help in a big way. I've been lurking and reading some material in the community but due to my heavy work schedule, I can't get nearly enough time to do proper levels of research and reading.

Here's hoping for a bit of help and some luck,

They’re either under watered or over watered. I would guess under..

try n get the humidity between up to 60+

air circulation under pots rise em up a little Would be nice

, coco must always be kept slightly saturated.. must not dry out at all, i think. Someone confirm?

Yes, although I must say I'm liking the coco much better than the potting soil I was using before, I really need to know how much saturation then, and preferably for how long, right now those NN's are consuming approx 42 OZ of water to get them decently wettened through, but it seems like they're drinking it up too fast and are still not getting enough and then are limp and sagging all over from needing more water, but then the above happens... -_-
Their soil is still moist, not soaking wet but damp at a quarter-inch or less depth. This is really vexing...

If your humidity is 40% and The temps run to 87 you’ll see more defined ripples and crab clawing, this With low water is causing this feedback, in my limited experience.

resolution, more water more often, keep humidity closer to 65 when temps run up. This should set you right I think. Via humidifier or water towels etc

..with a grain of salt as always

 

[Mrdudeman]

Okay then I'll try getting the humidity up, I'm just worried about mold becoming an issue, many of my teens are showing the claws curling downward, would humidity increases fix them as well?
Also, keeping humidity high in that environment where I'm running A.C. to constantly cool the room (which lowers humidity), keeping the humidity up with the temp lowered is a bit of a challenge, any quick/easy fixes for my rural self?
What's average optimum temp and humidity for a Veg room that's about 15x10, or just for Veg in general?

Water Coco at least once a day to at least 20% runoff, don't let the plants sit in the runoff, and always feed nutrients

I'm not a Coco grower but these are basic principles, you can search it right on this site; Goodluck

most definitely a difficult substrate.. often used in hydro and drip feed setups, typically flooded every hour. If I’m not mistaken coco cannot be overwatered, but I’ll have to check that I could be wrong. You may also run into nute deficiency as salts are easily flushed through coco in it’s high watering state

The clawing leafs will not unclaw, new growth will look normal

Agree way under watered... Pulling this link again cause I'm almost done trimming and lazy. Coco has to stay saturated with feed everytime. The media will build up nutrients and can mess up the CEC and will cause a complete lockout if it dries out. so I would flush with enzymes in ph'ed water with only cal mag added. Flush until you get atleast 2 times the volume of the pot come out. Then another full volume at about 700-800ppm with nutrients. Feed this amount with every water.

Up your feed to 3-4 times a day with 10% of what you put in coming out the bottoms. Test the ph and ppm of the runoff so you know if the media is correcting itself.

It sounds like a lot but once pots are saturated it doesn't take much to get 10% run off

Coco is fantastic you just have to use it right.... It's not soil.

This is your Bible. Read it like your on trial.

Buy a humidifier and don't get something too small for the job either, you can always turn a large one down vs boost a small one to do somehting its not capable of.

Disclaimer I'm not a coco grower... But that's your issues. Seen this sooooo many times so it's a common mistake and pretty easy fix. You will thank yourself for taking the time to read that article and having it on speed dial

 

[Mrdudeman]

You guys are all incredible, thank you so very much for the quick responses and excellent advice and info, I'm starting corrections immediately.

 

[Beowuuulf]

See this great thread by aqua, after you see The coco bible thread, this ones regarding humidity / temp and it’s effects

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

Just don't rush it and do it right. If no enzymes that's ok. Ph AND temp adjust and add 100ppm of cal mag and flush the crap out of it.

So pH adjust water about 70f (rough guess you wanna be as close to the media temp as possible), 100ppm cal mag and if you have enzymes use as directed. No need to ph or temp shock them when they are down and out

 

[Aqua Man]

May aswell ask what nutrients or additives are you using?

How are you mixing them step by step?

What is the source water?

Those plants are thirstier than a cougar at last call.

Hey dude , what's happening with the plants in the background
They look really healthy , were they grown differently than your problem plants or am I seeing something wrong ....
