Droopy seedlings. Light stress or overwatering?

[Lachrymology]

They're about a week old. 100% Coco hempy solo cups. Watering with only distilled water phed to 5.9

400w MH at 30''

Thdyve looked fine and vigorous for their youth. All but one had some drooping in the serrated leaves but nothing this exaggerated (I attributed it to weight. I do have one day wrecker x LBL that is reaching up with its leaves for the light).

I lowered the light about 8 inches and watered them slightly more than normal as the Coco around the jiffy pellet seemed pretty dry. Now I wish I hadn't done both, this would be easier to diagnose, but is what it is. I've moved the light back to where it was and ceased watering to see if they spring back. I had been watering about half a shot glass around the jiffy pellet 2 times in the 18 hours the light is on. Temps stay at about 74 RH is low at 40% and there's plenty of air circulating.

So did I overwater or did the light get them? They haven't recovered since I noticed this (about... 20 hours ago) and one is just going so strong but the rest are suffering.

Over watered

Would that also cause the serrated leaves to start to lighten up to a lime-grern color? They almost seem like they're "whitening" up a bit.

Any chance they need nutes since it's Coco? I understand the cotyledons should supplement the plants for a while but I hear mixed things about providing some nutrients for Coco after they're about five days old.

No nutes yet. Lay off water.

Wait till 2nd set of leaves man I use coco and that's when I hit them with nuets just let them dry out when I water when there young in solo cups I only water like once a week but that me man try not to over simplify things let them do there thing and I can tell you all the neg things going on right now is from over watering and try get a t5/clf they will respond slot better

That seedling is standing in too wet coco.
The only nutrient they need at the start is the P in N-P-K. This is used to make roots.
A shortage will make the stems look purple. I just feed my seedlings with aquarium water for the first week after germinating.

 

[Lachrymology]

Appreciate the input everyone. Just gonna let them dry out.

Pick it up and get used to the weight. Learn to only water when it is feeling light.

So they were doing worse today, particularly the younger ones. I decided to mix some new cups and add perlite since these things just weren't drying out at all. Also, news to me, those jiffy pellets hold so ooooo much water.

So it seems like the roots just stopped growing. Several of them the roots weren't even coming out the bottom of the starter pellets yet. I trimmed back some of the bag (from the bottom) and gently removed the medium until I could see some of the roots and planet the cubes into the new coco/perlite mix.

The tips of some of the roots were sort of greeb/yellow/brown (maybe the bottom 15% of the roots).

I figured I didn't need to water after this... "transplant" since the starters are plenty moist and the new Coco is optimally damp.

Is it possible for these seedlings to bounce back or will the ones with the canoed and drooping leaves die off? The ones that have the worst looking leaves seen like they're drying out in volume but aren't getting crispy. There's also miscoloring going on. I'm starting a few more beans just so I don't get too far behind since the last few sprouts finally finished up (not watering these at all and they're praying and looking great).

Any advice on further steps I can take are extremely welcome.

Bada-bump

Get some air flow going. It will help dry them out faster.

 

[whitebb2727]

Quite screwing with them and leave them alone. You are going to kill them pestering with them all the time.

Yup, point a fan at it and leave it alone.
I'm a weirdo, I prefer to mix in vermiculite to perlite.in my coco mix.

As long as the pot isn't too big that means watering maybe once a day in warmer periods, and every 18 hours or so when it gets cooler and more humid.

Jiffy pellets are a waste, let your seeds soak overnight in some kelp, plant them, keep up tropical temperatures and it will pop very fast.

Get new beans and a bag of dirt. Do mire research on coco if thats your groove. And use this as a learning experience instead of a mistake. This org. Has taught me how to grow. Joined at 14 years old almkst ten years ago under marley 408 or something. Cant find my old account. Either way if i learned anything from rollitup is that there is always somethi g to learn. One step back 2 steps forward. If you dont want to start from scratch then letting your coco dry out and seeing what happens from there is your only option. Patience is key. Sometimes results wont be seen over night. Remeber these plants mature over several months. So sit back relax and have fun. Other wise why grow. It should be stress off the chest not the other way around. Happy growing man.

Ive had them with fans on for 48 hours even cranked the 6 inch inline up near all the way to pull out every bit of humidity to help get then to dry. When I say this Coco was SOAKED still it kind of blew me away. The cups are at least five times lighter than they were the drainage was non-existent to say the least. It looked pretty clear how saturated it was that if I just left them they were going to keep deteriorating.

Coco is easier and faster than soil for indoor (outdoor too when it comes to nutrient management). If you do use soil, it must be fluffy and light with lots of organic bits to help drain and oxygenate the bacteria and fungi feeding and feeding on the roots.

You will kick yourself if you did a soil pot vs coco pot comparison. I have week-old coco plants towering above month old soil ones.

Put it outside a bit so it can dry out and get some fresh air.unfortunately, that plant will always be a runt. If you fuck them up in terms of root development or any other factor in the 1st week, they stay fucked.

They're gonna be dryed out now since I put them in new mix with perlite and its not soaked to fucking gills. I have some new ones coming up and two that are up that haven't been tortured like the first few and they're looking fantastic.

You seem to have enough light on there. I hate it when I see people sprout seeds and they go all Jack and the beanstalk in a day due to insufficient light.

Nah if I fuck this up I'm gonna fuck it up myself, not because I didn't get the adequate equipment. Dimmable 1000w cool tube.
