DWC started same problems as always?

ah yes its in rockwool, and its just a feeder tube going up to the net pot, pots about 3 inches at the closest , it could be over watering maybe pull the feed tube a bit back from rockwool?

so im pretty pissed off. I REALLY WANT TO KNOW WHATS CAUSING THIS. I've had this problem three times. I have boughten all new equipment and even still sterlized it, and soaked anything going in water in h202 and ph balanced.
There is foam in my reservoir, white foam. my ph has spiked back up to 7-7.5 after dropping it too 6 today. my res temps are at 65-70f outside temps are 72-77f, two bubbles in reservoir. lucas formula nutes aprox 100ppm. R/O water.
honestly i've spent tooo much money and crap trying to stop this problem from happening. I really want to grow in a dwc but its starting too piss me off. I would use h202 35% but no one can tell me where to buy some. Im probably going to tare it out today. WHAT AM I DOING WRONG. I would like to think that my system says im not a moron, but why does this keep happening i think everything is optimal. the only thing i could have done more is run it with a weak h202 but i cant find the food grade.

I will wait till the new growth shows signs of infection before chopping. but i noticed growth has stopped the last day. I also found a source for h202 35% i hope, a local water treatment supplier, not open till monday!

your system does seem overly complex to me.. possibly more things to go wrong or more things you can mess up by keep fussing over eveything

i do not do half the things you do when it comes to checking ph, using h202 etc etc i use nft which i think is more simple than dwc anyway and i do not have issues like this..

when i have had spare cuttings that i have no home/space for i have left them in a tub of water/food at the edge of the light .. before i can bring myself to throw them away they look kinda like yours, dehydrated burnt/yellow ..

so perhaps someone who previously said they look over watered, or they are not getting enough oxygen at the root zone, might be on the right track
i think its your dwc setup and light itself "hardware" causing the issue not the food or ph

are these tiny plants sitting in too much water, thats not oxygenated enough ?, or maybe even the opposite, are the roots fully reaching the bottom of the bubbling solution, maybe they are drying out a bit ? .. i would recheck all this as it seems your system is not "physically" working since it happens all the time

This is puzzling as you describe it. From your description of your dwc setup, to everything you've been doing, I can't think of anything you did wrong.

So you're running a light concentration of nute with lotsa bubbles? If there is nothing to absorb the dissolved solids in the solution, or the absorption rate is really slow, the bubbler will eventually create a foam.

Someone else suggested a lack of oxy in the root zone and too much fluid. That could be the case. But a simple water-logging will cause a temporary droop that is easily corrected, and the plant should keep growing.

So what could be the matter? I'm not sure. I think I'd have a much better shot if I could inspect what you have going in person. If it's not showing signs of noticeable growth, I would gently dig out some of the surrounding clay pellets to see what's going on with the root zone. If you notice new, white root strands that have developed since you first planted, gently put the pebbles back and know that there is still hope. If you don't see any new root growth, it may be the genetics of the seed? Were the seeds sitting around for a while before you germed?

Edit:
And ease back on getting more and more stuff like the food grade hydrogen peroxide. I doubt it'll change anything, and you're just gonna frustrate yourself by spending more money. I say that because such a debilitating contamination of a hydro system doesn't occur that easily.

Before I try to think this any further. Tell me about the seeds. Where'd you get 'em? How old were they before planting?

Remove that stupid tin foil or whatever you've got going on there. =P I know people use other materials to block out the light from the res but Ive never seen tin-foil or whatever you have going on there. My thoughts are the tin-foil/whatever are concentrating the light and frying the little *hopefully* girl. Try replacing it, cant hurt. Or go without it =P I dont have covers on my six net pots and Ive been fine (temps as high as 80-89 when I left for the weekend! I was pissed my roommate didnt throw in the frozen water bottles).

Hey, this dude might have something too. Take all that shit off the top of your bucket and let the surface of hydroton breathe in the open air.

its probably mylar

ah yes it is mylar haha i know the terrors of tin foil hotspots, I dont think it would be a lack of 02 i have two diffrent pumps and air stones i could even throw in one more tomorrow. but the ph spike is my biggest concern. from 5.5 - 7 in 12 hours is just crazy. My seeds this grow where bag seeds, a kush of sorts. before i had green house cheese, world of seeds strawberry blue and something else, always same problem, i should point out this is a diffrent bucket and the reason i used it was that i could make it light proof more easily. Im starting to consider this grow a failure, there was some new growth but the ph level is impossible to keep in check, and i 've read big ph swings cause lockouts too

well i checked and there is new root growth so im hopefull a little lol, im going to battle these crazy ph spikes with super low 5 ph top ups each day, i decided to go crazy as well and put in 3% h202 at 1-1/2 table spoons per gallon. This plants either going to live or die seeing how i was considering pulling it and cleaning shit up and starting again. Will also change the water monday and boost up nutes too 250-300 ppm

Try starting on a tray for your next attempt. Could solve the problem~

There's nothing wrong with what you did. Keep trying. You'll get it. Peace.

hmm still got ph spikes, and yellowing leafs a bit but seems okay just a pain to have to ph down twice a day.

I havnt touched my PH in 2 weeks ;P loving it.

New hydroton will cause daily ph rises. correct them to 5.8 and keep on growing.

ah i do soak my hydroton in a ph balanced solution for 24 hours anything that touches the water gets a soaking, same for rockwool. But my ph rised from 5.3 to 8 while i was sleeping. the plants still some how growing but i think it should be fried. Reservoir change today. going 250-300ppm with 5.5 ph, 1-3/4 table spoon hydrogen peroxide and im oredeing some hygrozyme today. hoping hygrozyme will solve this problem

Abort the hydrozyme! slime in a bottle!

hmmm anyone else has suggestions? i will look into both a little more

ah so reservoir change today. Think i found my problem. I wasen't sinking my frozen water bottle. so much slime hiding out in the bottom. So drained that crap rinsed out with bleach and water, filled up with bleach water mix threw in water pump and airstones, lets er go for a bit, then rinsed all out in shower and put in tap water in bucket and let run some more, then rinsed out, filled up with ph balanced r/o, put in 150 ppm, will probably bump in another 100ppm tomorrow. put some bleach washed rocks in bottoms of my water bottles to sink em. i thought the cold water would go down and be pulled in by the pump and kind of just disipate more evenly. But i did read submerisable pumps create heat so that could be why is was all in the bottom, top was clean. Not to sure if i should get the hygrozyme now that i spotted this. will let er ride for now.

Ah ha! So the plot (and the slime) thickens, huh? Glad you found the source of the problem.

Yeah, submersibles heat your water big time, dude. In such a small body of water, I would imagine it heats it up pretty quickly.

You're running a pretty straight forward DWC situation. Whatever interval you're running that submersible to feed your plant, cut down on that. Make your submersible's on time minimal. Just run it for a few minutes here and there to keep your top area moist. I can't imagine you'd need to run that pump much if at all. Some DWC guys don't even bother with the feed pump and just let the bubbles do the work.

Your plant should bounce back now that you cleaned out that ph crazy slime. Your thread actually bothered me a little because you were so careful yet your plant wasn't growing... I couldn't figure it out.
