What Sort Of Measurements

[zeusk9]

What sort of measurements do I need to put in my seedlings in 100% coco

I am using r/o water Canna A and B rhizotonic cal mag


What ML per Litre is best? for the lot
i was thinking
1 ml each pre litter to start then up it by 1 ml each week till are using 4 ml each per litter.
ps i do have an ec/ppm meater if that make things easyer

You don’t need to feed seedlings except some calcium since the coco lacks the required calcium and on top of that you are using ro.

Love to help not a coco guy, sorry. But there are lots of coco people here so any suggestions dude and dudettes?

But otherwise don’t feed them at least until first true leaves appear, their roots are very fragile at this stage and they have everything in their celulose spaceship.

feed seedlings 200 ppm and bump it up as they grow.

You are using coco so you need to keep the coco wet all the time but those solo cups don’t breathe at all so your roots could be rotting have you checked the roots? Is there a moldy smell coming from the coco?
I had the same problem due to my laziness at my water practices and they ended up dying just like yours, first cotyledons then the first leaves and then the plant. I don’t know much about coco so i may be wrong but thats what happened to me in soil.

Then there can be couple of culprits what is your rh? Max and min temps? What kind of light are you using at what distance from the plant?

50 w at 5 inches is a little insufficient for healthy growth but if you have the same problem with every light then i would suggest you check your roots closely, you are phing your water right?
