Over watered??

[Cooterjuice]

16 day old Beaver Genetics Sorbet Dream. Planted in 70/30 Canna Coco/Perlite. Botanicare Kind nutrients was feeding 500ppm (1Ec) 5.8-6.0ph. Once a day fertigation. Environment 80°F and 62% Rh lights on. 73°F and 60% Rh lights off. Dehumidifier running at lights off in lung room.
This sick girl started looking like this Sunday. Initially looked like over watering? Her 2 sisters are healthy. Any thoughts on what to do to try to save her? Pics in order of progression.

Looks like you helped me answer my question Tom. Hydroton is only thing holding her up. . First plant or seed I've ever lost.

That sucks, sorry bro. How do you prevent it? less fertigation?

Too much too early I assume. My other grow in my 2x2 I started them on daily fertigation at same time. But they are in 3 gallon pots. Roots just wasn't ready for that much water yet I guess. Learning experience. You can over water in coco when they are young for sure.

Well that's crap. Never mind. Gives you a chance to warm another bean up and mark that one to experience.
I usually go by size, but I think I don't start fertigating to run off till about day 21ish.

Yea idk if I'll drop another one in her place or not. Be 2 weeks behind. But then again it could be 10 weeks I could be growing something!!

Yeah m8, go for it, you will need to sort feed out at some point though as I assume they are all from one source?
