Is the rockwool constantly soaked by the water pump? Ive seen seedlings in rockwool that are too wet and they ended up looking like that... I don't really see the point having a water pump... I just let the net pot touch the water and the roots found their way down.

I think that was part of his problem. That slime he found at the bottom was probably the main culprit, tho.

I agree. I think he should nix the feed pump altogether.

An observation or 2..

1. keep your mylar hat on there... you want absolutely no light getting to the water..NONE. light will penetrate through the hydroton..
2. Next time let the plants get good and rooted before putting them in the system. I clone in cups of coco. When the plants are almost root bound in the cups I take them out, rinse most of the coco out and place them in the net pots with the roots hanging out of the pot. This alieveates the need to hand water until the roots are reaching out of the pot into the water.
3. I would highly suggest you check out the brew your own beni tea and following the simple directions. Especially since you already had a slime issue it could be the brown slime which h202 and zone will not cure. And its cheaper than h2o2.


Lastly, sometimes we are harder on clones and young plant than we think, sometimes they just need to work through the tough first couple of weeks and get settled before they start growing. There are always a couple "duds" to avoid this I start to veg 18 and then l down to the 12 best to continue to veg a and then flower. tHis avoid the pitfalls of all the eggs in one basket. Plus you can use the culled plants to experiment on. (over feed them, chop them in half, give them no micro nutrients) all things that will help you learn the signs of different problems and ultiately make you a better grower.

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 read your whole thread and can relate, but do not worry. First slime in small DWC system happens because of temps going to high so you have to control them better. Change the frozen bottles more often or use a bigger one. Second search for Brewing your own Beneficial Microbes on this forum and consider using a tea to get the slime under control and heal your roots. But most of all a little white foam is a good sign not a bad one, it means the "good microbes" are converting nutes into usable IONS for your plants to eat. If it does not smell and the foam dissapates quickly when you shut off your bubbler then it is what I said it was. Lastly your issue with PH is from the slime it will cause PH to climb to 8 in just a few hours. What are you using for PH down? I had this problem when using vinegar, it would not hold the PH. I switched to GH PH Down which had 3 acids to buffer the water and my problem went away. Oh and slime will turn your plant yellow as it robs your roots of nutes. Good luck to you bro keep trying.

IMO I would clean your res with H2O2 and I also suggest using zone at the max strength after the clean out. IME I had to suffer through some high res temps before I went to coolers, and the only thing that saved me was zone. I found if I forgot to add it by the next week I would start to get slime. YMMV and honestly these guys know their stuff so I think they will get you sorted out especially if you go the organic route. Good luck and happy growing.

passed out earlier then normal but going to do another res change, bump to 400 ppm, 300 seemed good. do a little h202 pour through my cubes and a dip of the roots. start brewing a tea with just ewc, until heisenbergs tea supplies arrive. Hope she survives new growth is always there but stunted so bad from slime and ph.

Bubbles and foam

slight lack of nitrogen?

thats it sorry fell asleep early last night so today is pics
also more growth when i woke up this morning. But a high as ph and more foam thus the res change today.

can anyone tell me if using just ewc for a tea will bread benificial bacteria and fungi?
i am trying to avoid enzymes as heisenberg said they where bad in dwc.
Just waiting to buy some bonticare aquaclean and zho poweder as additives to make a proper tea but need a quick attempt fix

yes it will but it wont be a effective as with myco or great white but it will be a good start.

Looks better! Yeah, give it more N.

Edit:

Or it could be that there is enough N, but your leaves look slightly yellow still because of the 'struggle time' they just had where they couldn't absorb the nutrient solids. Since they're growing now and you see root hang, they could very well just outgrow that yellowness without any particular increase in N. I've seen it before.

sadly its out of season and damn impossible to get earthworm castings unless i drive like 3 hour trip there and back. so i payed the shipping and now i must wait. probably be doing bi weekly res change untill tea is ready. Found a nice h202 3% that has no stabalizer (my friend uses ones with stabalizer but you dont know whats in that.) just purified water and h202. probably put in 5 tables spoons for good messure in 3 gallons. I hope that my tea supplies arrive in about a week and hopfully she last that long.


I also started having high ph spikes again so thats part reason for res change.

Bubonic, consider going the clean route. Zone works for all but the most severe cases of root rot. Have your roots even made it down to the water level yet?

ya my roots touch water and i got some super white new ones! (hope lol) im going to make a tea that is suppose to be amazing according to most growers. Apparently its strong enough to not watch res temps and no light proofing. They used it in a clear container and had no problems. and its super cheap like 5 crops supply 50 bucks

everything has been cleaned up again. I think its cause i neglect to change the water bottle till res temps reach 70 or i go to bed that. the slime came back not much more but more foam lol. there on 250 ppm. the res itself is 350. h202 at 1-1/2 table spoons a gallon, ran some water h202 through net pot then dipped roots in h202 water then rinsed through net pot with just water. i turn my res pump on about 3-5 times a day.

the humbolt myco madness seem to be the best but as long as you brew it for 48hr your going to be alright!
but you will still have to keep water temps bellow 75F to have a effective tea

Ok, I have a few things to add after reading through all the posts. This is what I have gathered from my experiences.

When I switched from tap to r/o I had the same ph nightmares as you are having. When you run r/o water with low nutes, there are not enough buffers in the water to maintain the ph. Once I switched back to my tap, Voila! Ph problem completely gone, hardly drifts now.

My tap water read 350ppm. Supposedly that is too hard, but my plants love it. And the end results have been amazing.

Back in the day when my PH was off without my knowledge, I would add more nutes to correct the yellowing leaves, but then once the ph came back around a serious nute burn would occur.
You can try a ratio of tap and r/o and see how that treats you...

Now for res temps.. My temps are at a constant 80-83 when lights are on.. The roots are BRIGHT white, and have the perfect fresh cut potatoes smell(never had a problem with diseases, maybe something in AN). So I would say the res temps are not the cause either.

She is looking better, good luck.

well no ph spike in 20 hours, awsome for me haha holding a steady 5.8 which is my ideal. res temps dont go above 70 now even after sitting for 12 hours with just one bottle of ice. Hoping for that explosive growth cause my roots are almost all in water. Yep she seems okay for now :)
