WTF does this mean?

here we have the Fly Hooker at the back and the Grapefruit Fly in front, still looks like more are fighting to pop the surface.

Im a little confused........
Im not a hydro person so please forgive me if Im wrong.
But shouldnt you start the seeds in the plugs and then put them where those holes are in the RW cubes?
Also, shouldnt the RW cubes be covered so there is no mold growth on them?

 

[exploziv]

Maybe the algae growth is consuming nutes and that's some kind of deficiency? Never seen it in soil.. don't know what to say.

Hope they'll get better soon! Keep them growing!

 

[Guest 88950]

could it be a natural varrigation showing up?

 

[yortbogey]

maybe a ph drift w/ the rockwool...???or there screaming for more cal-mag...???

 

[abellguy]

On the one in the pic under where it says WTF it looks almost like a variegation, but from the other pics the slight yellowing looks more like some type of lockout or deficiency. I've never grown from seed in that format before, so its hard to pinpoint.

When working my cuttings as soon as I see the first roots showing through the cubes I start to feed what I soak the cubes in which is ~.8 EC ~5.5 PH consisting of Field 16 a,b(which has plenty of cal/mg), rizo, and zone.

Most are sprouted and on their way though, I'm sure they will settle more as they get a little bigger

cheers man, most look ok so far, time will tell...

you are not confused, ideally speaking you do start seeds in smaller cubes, but when you been doing this as long as i have, you some times just improvise with whats around. having done it before in other locations i know it does the seedlings no harm to start them in the 5 by 5 cm cube. the hole in the middle is actually handy when hand watering, it helps the water get absorbed. the algae growing on top, is also more of a theoretical problem then a reality based one. after the first week or 2 the cubes get shaded and the lgea dies off. i have never seen even that black thick slimy algae, cause any harm to the plants in a drip irrigated coco setup. i think it's because you are providing fresh nutrients too regularly for the algae to be able to steal enough to have any viable effect.

based on previous experience treating seedling exactly this way, i can check those off as potential reasons for the funny yellow stripes.

thanks man, but as i mentioned above, it's unlikely as i always have algae on my cubes at certain stage and it's never caused this side effect before. i have a suspicion that it might be connected to the so called off gassing phenomenon. but i thought i took the offending pond liner out. also last time they all looked really yellow. this batch of seedling looks much better. my trays are made of pp50 which is all thats left thats different to my other set ups.

could it be a natural varrigation showing up?

not likely, every other time i have done things the same way with same ec level and ph and never had this problem till this new room. i will get to the bottom of it sooner or later lol. i thought it was solved till i saw that seedling.

maybe a ph drift w/ the rockwool...???or there screaming for more cal-mag...???

cheers yortbogey, ph drift is some how unlikely, but i guess it's possible. maybe i better recalibrate the meters. so far i have never needed cal mag to pop seeds in rock wool. but i suppose it is possible that this strain is more cal mag needy then most.

On the one in the pic under where it says WTF it looks almost like a variegation, but from the other pics the slight yellowing looks more like some type of lockout or deficiency. I've never grown from seed in that format before, so its hard to pinpoint.

yes i tend to agree some deficiency is taking place, i just doubt that it's related to the nutrient solution i'm using. i intend to plant them in the coco slabs tomorrow, then we should see rapid improvement, unless it is the original laminate floor in the location that is causing the off gassing? but then it should have been fine when it was covered with the pond liner. man it's a puzzle. i read about this crap, but never been so unlucky to have to deal with it.

thanks everyone for your input.

 

[Guest 88950]

i mentioned varigation b/c your no noob so i eliminated user error.

i hope you find the source of the issue.

peace

 

[gaiusmarius]

sorry man, it looks like i was answering some one else. some natural type freak was my initial hope, as we see, one or 2 others of the same strain are doing it too in a lesser way. i'll know more tomorrow, just got to hope i have the strength and energy to do anything tomorrow, it seems i'm coming down with a flue....

Planting Day

the greapefruit fly is still showing those yellowing symptoms, some of the afghan diesel x is doing it too. i'm hopping now that they are hooked up to regular feeding in the coco things will get better. otherwise i still haven't solved the problem in this room. time will tell...

as you can see they are not all suffering the same way...

Hey Gaius,

I'm coming in late, but that just means that I get to see the progress faster Very nice play room you got in there, and with them beans, you'll be rocking the place with flavours

Being an outdoor dirt player mysef, the thread has been very useful to pick into other systems Coco slabs, eh?

Take care and happy growing!

[Hammerhead]

I keep forgetting the name of those ballast ???

EDIT:I found it gavita

 

[exploziv]

It's great to see such an well organised and clean grow! I love it so much I'll stay here waiting for your next updates.

congrats and good luck with them!

 

[VagPuncher]

Flip em!

nice to have you along B, trouble is i'm still not sure if i managed to stop my off gassing problem. plants grow really really slow and look pale. have covered all the visible flooring with cardboard and then added a layer of panda plastic at table height, to try make a buffer area between the floor and the hps lamps. we will see if this gives the plants a chance to prosper.

I keep forgetting the name of those ballast ???

EDIT:I found it gavita

actually these lamps are philips original. gavita has their version made for them by philips. the one i have has no dimming ability. it's a fantastic unit, never had a lamp that stays as cool as these do. they also run silent.

It's great to see such an well organised and clean grow! I love it so much I'll stay here waiting for your next updates.

thanks bro, it's a set up i have built many times over the years, it has never let me down. makes this offgassing shit much harder to bare. never have i experienced anything like in this room. already took out the pond liner thinking that was the cause. i really hope the buffer zone between the lamps and the floor material might do the trick? if not i'm really baffled.

Flip em!

i would, but they are not growing how they should be, i want to have them healthy before i flip. even if i have to cut them back. if i solved the problem with my recent action i'll be able to flip within days.

will take some pics again asap, lets hope things get better, else this will be a shity grow thread.

 

[Moppel]

heya man, i am popping in late too.... any new pics?

 

[gaiusmarius]

heya man, i am popping in late too.... any new pics?

hi ya Moppel,

not late at all. i only just resolved things i hope. will switch them tomorrow if they continue to look better. i really would like some information from someone who knows more about the whole off gassing thing.

a few days after blocking the light from hitting the floor material they are looking a bit better. but i still can't be 100% sure i solved things. never have i had to deal with this kind of shit in a new set up.

here some examples of the yellowing and the pale color as well as the thin stems. this is not normal after all this time. in my other setup the same seeds will be ready to flower within days of popping.

so i covered the floor with cardboard and made a double layer of panda plastic at the hight of the tables. i'm not sure if the hps has to hit the material to make this gas, or if it's enough if it gets warmed up?

check out these seedlings, they popped from some seeds that got flushed down the table and found a place near the drain. i already tooka couple of them and planted them in some spare spaces for a test. interestingly those i planted later since i did the thing with the floor are growing healthy so far.

the one other possibility i guess would be the water. we generally have great water quality where i am, but i suppose i better consider all possibilities and get an ro filter in asap too, specially if things don't vastly improve chop chop at this point.

update to be continued...
