It started couple days ago and is looking worse everyday. Clones with roots, topped.

Fed them with 50% a+b and 25% calmag and 100% hydroguard. Lots and lots of Runoff. PH 5.8.
30/70 coco perlite.

Thoughts? What is causing this?

Over fert. Low pH. Transplant all into 3 gallon pots full of FF light warrior soil. give nothing but water that isn't pH adjusted. When they get about 1 foot tall, transplant into large containers of FF ocean forest soil. Give nothing but water that isn't pH adjusted. Large containers like 10 gallons each. It's a lot of soil but that soil is good for indoor grows and doesn't require anything for a long time if you use enough of it. Don't put up so many pics next time. 3 max to show problem, one of whole plant, one that zoomed in, and one that is a close up of good example of the problem. What soil is that?

Bright green growth is not out of the ordinary at that stage.
Whats the EC/ppm of your feed?
How often?

I feed my coco at ph range. 5.8 thru 6.1.
Vary up/down thru range every few days for better uptake.

What are those green cheese-grater looking covers in the bags for? Are those just to slow down the process of moisture evaporating? Floraflex caps, used to spread the irrigation more evenly. A properly fitting cap can help mitigate evaporation as well.

I was gonna say — that is weird when the new growth looks worse than the older leaves. The above posters probably know better than me but I would also advise slowing down on watering? Those cups look wet.

I think u may be right, too high ec maybe.

That said:
- Not gonna change to soil
- I think u missed the fact I'm in coco/perlite, how is 5.8 too low pH?
-only do 3 pictures is this a joke?

Not sure about ec but I think in the 0.85 area. EC on the plant I cut them from had higher EC than they are getting now, don't know if it matters?

Maybe every 5th day full soak and lots of runoff, practically flushing them with nutes. I don't have a schedule for feeding them atm just lifting them up feeling the weight and looking for surface starting to dry.

I'm aware new growth can be bright green which turn darker in time, but this bright/yellow looks weird compared to what I have seen before on their mother's.

Right? So weird.
They are very wet cause I fed them right before taking pictures. It's coco perlite though so they drain well.

You are supposed to be watering to runoff every time. Ideally multiple times per day

I do water to Runoff every time, plenty of it. Don't need to water daily though it is optimal. As long as it don't dry out I can feed twice a week no problem.

If you transplant to good soil like OF, you'll be giving the plants the opportunity to pull those nutrients out of soil. If you over control the grow, which is what happens in coco and why so many fail, you will continue to have problems.
You can put a coco plant into a large container of soil. Your containers are very small and ideal for a switch to soil.
Taking more than three pics to show the problem is a waste of time as it's redundant. We only need three good pics. Any more takes more time to view and space in the thread, which is pointless.

I can assure u I would do worse with organic stuff :D I will have problems either way its my first around. Though I find coco to be very nice to grow in and I want the faster growth from hydro.

Taking three "good" pics is the key word, and why I took so many.

Plants I took these clones from are doing great and I did have my fair share of problems when in Dwc but coco felt forgiving.

How so? What u think is causing the syntom?

It's also recommended for hempys regardless of medium. Good luck to u 2

Boatguy says that because you're over doing it on the nutrients. You have some leaf tips that are yellow/brown and dying, which is typical of over fertilizing when the leaves are also kind of a dark green color.
Are you sure that Hydroguard is necessary?

coco seems to difficult as it has no nutrients and growers usually get the feeding wrong. coco traps water and nutrients. I would think you have to go easy on those ferts, but then I've never used coco. it just seems logical is all. Compare it to DWC which has a lot of water, the dilution is going to be high if you don't use 800-1000 ppm. In coco, I'm guessing you don't use so much, but that's just a guess.
