How often do you water the pots?
How often do you water the pots?
Have you heard of over watering? That could be the problem right there.Every day. Almost 2 liters in a 3 gallon pot.

Looks like a combination nutrient build up and to much light. Do you have a zoomed out pic if the setup before you moved your light?
Does not look over watered to me
The plant s pretty small to be needing much nutrients at all. A plant that size can live off of a single feeding for a month or more. Once they get larger they use a LOT more nutrients, but at this point, they are just taking up space and possibly being overfed or locked out. When I first saw this post I thought that the plants were a few ft tall and growing robustly. The small size changes things considerably. Everyone here has given good advice. I grow in Promix and not Coco, so I can't give you 1st hand advice with Coco growing, but with Promix, I water daily or every other day as needed, and feed every 2 weeks after they get roots coming out the bottom of a 5 or 6 gallon bucket, usually a month.Think @oldskol4evr and @Jimster have ya covered. The leaves are darkening because it starting to uptake nutrients again (a good thing) but as suggested I would lower your ppm especially for plants that young. If your ppm is still high coming out you may want to flush again and do a light feed.
As far as overwatering I would not be concerned one bit in coco.
I'm no coco grower but a plant that size I would think 2-300 should be plenty.

In any event, it looks like you have turned the corner and things are looking better. Keep up the good work, go easy on the nutes, and you should be good to go.
That's what I practice and preach fellow bud
If you're growing in media (Coco media) why do you water when it doesn't need to be watered?I have but in coco coir it shouldn't be an issue, or so I've read. Although i did wonder that because the soil is always so wet.

Not in coco and roots don't need a dry cycle. They need water nutrients and oxygen. Look at hydro for example. Not all mediums have the same needsIf you're growing in media (Coco media) why do you water when it doesn't need to be watered?
When growing in media filled pots you want to use the right size pot and water once a week to prevent over watering, roots don't like to be wet all the time they need their dry cycle.
Using Promix, it is my experience that the media doesn't like to be dried out to the point that the plant shows signs of water deprivation, but they do enjoy a damp media. Roots love damp conditions with plenty of O2 available. If you can squeeze more than a few drops of your media in between waterings, then you might be using to much water, but Coco and Promix are pretty resistant to that due to their water shedding properties. I use 5 or 6 gallon buckets and the water dynamics are much different than smaller containers, which dry out much faster.When growing in media filled pots you want to use the right size pot and water once a week when the pot feels light and not heavy with water when you lift it to prevent over watering, roots don't like to be wet all the time they need their dry cycle.
Roots that are always wet in media have problems like slow growth, root damage that looks like deficiencies, plants that beanstalk and have no branching even gnats.
Just because Coco can't be overwatered you shouldn't try to, plus why do you wanna replace the water nutrients solution before the plants have a chance to absorb it all, it's gonna take a month for that plant to eat all of the ppm and people keep feeding her twice a day? Just seems like a waste of nutrients and a bunch of unnecessary over watering?
Because coco isn't soil. It's a soilless hydroponic medium. Twice is on the low end. I'm usually at 4 or more by the end of flower. Not to mention not to many people use pure coco. It's mostly cut with a lot of perlite. Wet coco still has a ton of air to the roots unlike soil.
That's a pretty general statement based on not knowing pot size or plant size. A 200 gal pot of coco is going to be way different then a 1 gal pot.
You aren't overwatering (but you can) by feeding them daily. You are keeping a constant pH/feed in the root zone since when coco dries out the pH and ppm start going haywire, like most hydroponic mediums. It's about managing the medium since you aren't using something like lime to buffer pH and N uptake will effect medium PH.
If the worry is about saving nutes and not wasting them and water then coco should never be your choice in the first place unless it's in a monsterous pot. Kind of goes against everything the medium is tuned for. You would be better off in wool.

Have you grown in coco or hydroponics? I'm just curious because Ina previous post you stated you weight the pots and water once a week. That's a totally different principle for a totally different style of grow. Generally coco is drain to waste and yes it seems wasteful because it is and is intended to be. It's about increasing growth rates at the cost of wastefulness.The idea is the plant roots don't like to be sitting wet all the time and the plant can only absorb so many PPM per week , anything more like watering and feeding the plant four times a day is just a waste of nutrients and a bunch of over watering .. who cares what the coco can or can't do ?? so i can feed the coco four times a day but the plant only eats X amount of PPMs per week, all the rest goes to waste ...

Roots don't give 2 shits about being wet, they actually like it. They care about available nutrients, water and oxygen. Look at full hydroponics for example.
Now comparing to soil as I think you are. In soil to much water to often is held by the soil and does not allow adequate oxygen levels for the roots. You can't apply the same logic to soilless. It's just not the same.
Ok so my hydroton is media. Do I water my plants in hydro once a week?coco is media
