droopy seedling leaves

New grower here. The leaves are looking a little droopy and cant seem to figure out the problem. The seedling is two weeks old today

100% coco
600w mh little over 20 inches away (was at 450w till this am)
oscillating fan since it sprouted
water ph 5.8-6 usually every 3 days (pick up cup for weight usually feels like air when i water it)
i get bout 5-10% run off every water
current temp 77 and humidity 31 (temp range 64 at night-81 is highest and humidity 27-46 but generally hangs around 30
no nutes yet

dude you burning shit out of your plants, use cfl till they sprout 3rd set of leaves and then dimm the mh down ,

Agree^^^
Or overwatering

I'd give them a little nutrients at two weeks of age (or personally, I would have started with weak nutrients from day 1 in coco). JMHO: I don't think they are heat stressed (77 is a good average temp anyway).

Edit to add though, there's no need to go a full 600w yet.

I backed the light off a couple inches and dimmed it to 300w. Since third set is starting to come out I figure I'm not gonna bother getting diff lights set up and thx for the help. I'll add quarter strength notes in my next watering

you're ready for 1/4 strength nutes, 200-250 ppm is good. you have 3 alternating internodes, she's hungry. it's even yellowing, which says i want nitrogen. get a good 15-20% run-off. they're also ready (over ready) for larger container. you'll see that the roots are now circling the bottom of the cup. leave it too long, and you risk stunting...

If you're a first time grower I wouldn't suggest Coco! It's for hydro because Coco doesn't react with anything, you have to provide absolutely everything nutrient wise it needs the whole time its growing..I'd also suggest that since you're in Coco to use hydro pH of 5.6-5.8... Any variation from this will actually start to lock out some elements from being used by the plant... I've got a thread in here with a chart showing this... Anyways . Looks like over water is causing the drooping, but not the yellowing.. Probably not light burn, leaves curl up, dry out and get crispy and brown from light burn, they wouldn't droop, most deficiency cause yellowing of some kind... Better pictures would help more accurately diagnose.. The pictures look like Fe Deficiency, N is generally uniform and starts from the outside in, Fe starts from the base of the leaf and So does manganese Def these two also make the part that is not yellow, turn darker green where as N just turns them yellow

As long as you give it some nitrogen like the other guy said it is showing some signs of defficiency, check a bit of calcium. I myself only use organic and no fertilizers despite their claims of being organic, i stick to fish and blood meal along with dried fruits and tea water solutions because they aid in microbial growth which automatically regulates the PH for you. usually synthetics kill some microbes therefore the PH needs to be manually adjusted. Really its preference but i only use around 150W for a single plants and it gets pretty huge if you vary the spectrum during veg and flower along with position and cropping for the leaves to get maximum light.

Thats why it looks like shit. Coco has no nutes, especially that husk your using. Feed hydro veg nutes ASAP. Next time feed from the start.

i was just going with all the stuff i read about no nutes for first few weeks because it has all it needs from the cotyledons. Transferred to a dwc bucket today with 250ppms of nutes so shall see how it fairs.

Don't use that shitty soil, I'm using it and now my fucking plant is dying... Fuck that soil, dirt, compost whatever you want to call it

A lot of people don't differentiate between soil growing and growing in inert mediums when they give advice I've noticed.
