Plant has discoloration from lack of light?

Here is my seedling its about a week old

coco coir.. its northern lights auto.. perlite.. absolutely no nutes


the inner parts of the leaves have turned darker.. (cant see it in the photo) i dont think its a nutrient def .. i have been to the stickys and cant seem to figure it out.. could this be from lack of light..

up until yesterday it was about 7 inches away from a 125 cfl.. now i have a t5 and its getting plenty of light

Over-watered and yes bring your cfl bulb closer

Make sure you run under a 6 ph with Coco! You know that it's inert in nutrients! Start the light feedings grower...

Over watered as previously stated, and you need to feed it at 1/8 to 1/4 strength nutes.
lol not overwatered. Have you even ever grown in coco? Try to overwater a plant. Especially in coco and perlite, won't happen. You water daily, to runoff in coco.

Give the thing nutes, water it heavy to runoff every day and let it go. I feed some seedlings 500-600ppm and if you don't let the soil dry, and don't let the salt buildup in the medium you won't have any issues. Keep pH good, boom good to go.

Never grown in coco, always promix +25% more perlite, would mixing some coco in with pro mix make it drain a little better?

Yeah coco has awesome water holding capacity and once it absorbs it's maximum, it won't absorb more (thus why it drains so well) where soil can get waterlogged quite easily and thus why people add perlite. I wouldn't recommend growing in any soil straight from the bag, but most coco could be used straight (once rinsed in case of salt since coco is created in a salty environment). You'll find that at one point, you might be able to make an organic coco mix instead of soil and you'll be amazed at growth-drainage. If you mix soil and coco, use the soil pH range, if you're just using coco then it's coco.

Note: OP check out the CNS17 line from Botanicare, and for the first two weeks use CALMAG IN COCO, ALWAYS. The coco will rob your plants of all the calcium you give it for the first couple weeks until it's banks fill up.

Its over watered for sure. Tstunted growth is a sign of over watering. Think how much that sprout can drink and then think how much youve given her. As has been stated, theres no nutrition in coco. It needs low low strength nutes nowish. Cal mag soon but not now as per pp snob and i dont think it looks stretched at all. That cfl was doing good by the looks of it, dont over light it at a young age by pulling it too close. Looks good if you let it dry out and feed it lightly. Cheers m8

Stop spreading misinformation. It is not overwatered, at all. Look at the coco it is dry. You know what else is a sign of stunted growth? Hunger. Think about sprouts in nature when they get dumped on by the rain in the spring, and absorb all the nutrients they need in the ground, in the wild, sprouts of all species, not just marijuana.

Give it 1/4 strength nutes, or even half strength, it won't hurt it. pH it to 5.8. Water it until you get a decent runoff out the bottom. Give it another watering 2-3 days from now depending how fast the coco starts to dry. Don't let it get dry all the way because then you'll have more salt buildup from the nutes drying up.

Specifically don't do what Alien suggested and do NOT let it dry out. Then the plant can't eat anything because coco is a HYDROponic medium and without water it cannot eat or consume food.

It NEEDS FOOD and it also needs CalMag right now for the first two weeks or else the coco will consume all the calcium that you put into the medium and the plant will get none.

Coco is not soil at all, it needs to be treated like coco.

When you say give it calcium/mag.... should i buy cal/mag plant nutrition and add it to the water?

what the fck is wrong with u people that thing is a seedling feed it nothing is has enough stored energy for at leasr 2 weeks thats fckn nute burn look at the tips leave it the fckn alone until u see leaves getting light then go 1/4 strength and so on all thes fckn dumb asses telln u the wrong thing i dont touch my seedling with nothing but water until the sec or third set of TRUE leaves look at my threads results dont lie all my plants look the same always huge with rarely any def

u say u gave no nutes then thier somtething in the soil releasing fertz i dont care what anyone else sais its not heat stress my t5 are practically touching my plant so eliminate that in my opinion u have something in your (soiless) mx releasing some type of ferts
