aero. possible over water? pic

This is my 10 day old blue cheese seedling, germed in jiffy pellets.Out of the 5 i germed 2 are fine with some decent root growth. The other 3 are a little stunted and the one in question in the pic is just drooping down.

Set up is aeroponic x-stream 12 site res and dome. Removed top of dome 2 days ago.
Had watering on 15mins per 3 hours. Still looked same.
Went to 15 per 12 hours. Still same.
Must mention because they are in jiffy pellets they hold water better.
Now ive moved to 15mins per 6 hrs.It looks like over watering to me but nothing seems to make much difference

.Using bio bizz nutes in res. Only very small amount dnt have ppm meter yet.Small amount of grow, and a little of bloom as this seems to have more micro nutes in.
Any help well appreciated. Think they should be alot bigger for theyre age in aero. *

Must be an aero grower whos seen this before.

Whats the brown stuff On your Roots ?

Well I'll just give my two cents on the matter I'm still on my first grow so don't take anything I say as SOLID information this is just from my experience so far.


You had a ton of moisture for 8 days, roughly 4 days with seedling appearance, I think you got the humidity way up for what it actually needs. Normally (cuttlings) need about 90% for 48 hours (someone correct me if I'm wrong) after that you should cut it out. Now if it's a seedling I don't think they needed that much humidity. I run my 80 site aero cloner 24/7 with some light nutes never have had a problem like that, nor did I use the dome and I've had 4/4 successful clones lol. She should perk back up in a day or two just keep the dome off! Also I didn't even use a dome for my seedlings in rock wool in a bubbleponics system try to stay away from it unless you really need it, as it has the chance to cause mould, fungus, root rot, ect ect ect.

The brown stuff is just the a little of the jiffy pellet medium wsshing off the pellet when qatering kicks in.

*watering*

okay i spent all day yesterday and today battleing the fucken brown algea thats what you got you probly got it some light leaks and its spead wild it only takes a few days it will spread the light leaks threw the fucken baskets man its crazzzy i been in veg one month and a half i cant trash the plants i been waiting 8 month to see some of these and i just cant so you with the early signs of algea dope your water ph your water at 6.o with bleach at two cups per 40 galons take the babies out and run constantly dump water after a few hours run on the second dump physon 20 on the third run h2o2 and on the final run just water make it like 24 hour runs to eliminate the brown algea... make shure temp is 65 to 68 airstones and dont run any organic or mycros yet untill you kill the pythem or brown algea... good luck its a bitch..

ow organic jiffy not a good idea in aroe ...

No probably not. But most of what can wash off has washed off and seems okay now changed res twice and no more bits going in water so should be ok now....
You think it wipl be ok tho n aero or you think the pellets hold onto to much water?
Only decided to go aero after id germed my seeds in pellets.
Roots still seem to be growing but plant growth is slow. And leafs on this plant are stilp drooping.
Any suggestion on a water schedule on a 15min timer and jiffy pellets.

Thanks for the input man. All help appreciated. You grow aero thump?
