DWC still having trouble's. Need Help ASAP

[dankdadank]

Ok. I am using a dwc system with two flourescent dual spectrum 65 lights. It has a 6 gallon resevoir. I am using tap water with a ph of 7.5. Also i am at 12/12 lighting right now. I am also using an organic micro and bloom. Last week i had a problem trying to get control of allgae. I flushed my whole system, water lines, air pump and the air disk yesterday. Now today when i went to go check on them this is how they looked. The ph is 5.65, water temp at 68 degrees and the air temp about 74. Humididty is alittle low at about 35 percent. The smaller of the two plants is my orange crush. That plant started drooping yesterday before i flushed it. And the lager on, Exhile, was real perky this morning so in the last 10 hours or so is when this really started. Any idea's on how to save my babies???????????????????????????

Please if some one could just help me tonight. i dont wnt them to die.

Flush them with what?

[Weedhound]

Fill out Stinky's troubleshooting form at the top of this forum for me and I'll give it my best shot. But without good info, you won't get good help.

That looks like an H2O2 bottle in pic # 3.
Perhaps that's what he meant.
Howzit, Weedy?:)

[Weedhound]

Yep, heres to hoping the full strength stuff is NOT what he flushed with.

[Revanche21]

drooping is generally caused by too much water

try adding another air stone

this helped enormously from my 2nd grow to my 3rd grow by adding a 3watt air pump

maybe the algae is covering the roots from getting oxygen

maybe try flushing a few times to get the algae off?

I use Hydroguard from Botanicare's line-up and I think it works better than when I used H202

good luck!

[dankdadank]

well, i ended up getting it straightened out. I flushed the system and started using frozen bottles of water to help keep the temp between 65-70, to keep the alge from growing. it is really hard to stablize the temp when only using frozen water. but any ways the smaller of the two never did come back to life. and the bigger on was a male. S***. So now i started new one's and they seem to be doing great. but i am using powder for my nutrients and i hate it. anyone have any good place to order liquid nutrients?

[Weedhound]

Don't buy mine online so nothing to offer there but glad to hear they are improved.

you might want to try sealing the container better. alage needs light to grow so you probably have a light leak. you should try planting 4 at a time because a 6 gal res. wont support 6 plants to have full root systems

what about just spray painting the tube black. do you think that would help?

[dankdadank]

well here's what the new one's look like. i got this white powder substance on my nutes. i cant figure it out. i took a picture of it. so maybe someone knows.

[stinkyattic]

That's salt buildup. Did you rinse your hydroton between uses?

[dankdadank]

I Just got the nutes like two weeks ago. I rinsed them the first day i got them. Then before i put them in the pot's i rinsed them again. maybe just not good enough i guess if i got the salt building up. but will that be alright for a few more days. im trying to keep them on a schedule with feeding.

Aloha dankdadank,

Just to eliminate any confusion.

Those little orange clay marbles are called Hydrotron pellets.
They are your grow-media.
New Hydrotron needs to be soaked in PH 5-6 water for a day or so to neutralize it's natural alkalinity.
Then rinsed thoroughly before use.

"Nutes" is short for nutrients.:)

Hope you are not trying to feed new seedlings.
They should have no nutes for the first week or so, just water.
Then it's best to start them with 1/4 strength for a while, then increase the strength slowly as they grow.

Different strains will require/tolerate different nute concentrations. So it's best to increase the PPM in small increments.
If the tips of the leaves start to brown, back off a little and you should be "in the ballpark".:cool:

Painting the tub black, or wrappin it in contact paper, or foil, or duct tape will keep the light out jus' fine.
I just set my tubs in a black plastic trash bag and then cover the top with Reflectix.
Keeps the light from the roots, relects the light to the plant and catches spills.:thumbsup:

Havin' fun yet?

Weezard

[dankdadank]

Alright i will have to put my rocks back in there for a day or so and let the nutes sit in the water. appreciate the help:jointsmile:

it looks like there is algae choking the roots of your plants and eating all the delicious nutrients.

your reservoir needs to be light-proof, buy a roll of metal tape from home depot (should be near the ducting) and tape up every inch of your res until it is PITCH BLACK inside, even (especially) the top, anywhere you can see blue, needs to be taped.

I've tried duct tape, spray paint, black plastic.. the metal tape works by far the best, and it keeps it insulated (probably).

should solve the pesky algae problem... also throw in a few mls of that Hydrogen Peroxide daily to kill algae while you procrastinate :p

[MichiganAero]

Im a huge fan of hydroguard. I love that stuff.. My hydro guy told me the Govt is forcing them to change from liquid to powder form. Something about proper use of chemicals.

I've had a few algae problems in my E&F and if you use the proper amount of hydroguard, it takes care of it every time.

peace
