Just can't get it

[hannuhuu]

Hi
Just started dwc hydrogrow. Root rot is getting the best of me. I have two layers of tinfoil around the reservoir, two airpumps pumping 600l/h. I'm using h2o2 15ml per 35l and bio nova nft aqua nutrients 40ml per 35l. Ph is around 5,5 and water temperature is around 20celsius maybe?
Just lost two monstercropped jack47s to root rot and my new Diesel Ryders are showing the same symptoms. A slime is developed on the roots and they are getting a little brownish allready.Where's the problem? Allready thinking of going back to soil because of this.

Oh and I've changed the water in the reservoir every time I see the brown slime.

Forgive my ignorance but is Bio Nova organic? If your water temps are pushing 70F and you're using organic liquid in dwc, that could be your problem......not sure if this helps, but with the air pumps and blocking light, you've ruled out my first to guesses.

I'm guessing the nutrients also. It's for hydros but my bottles have been opened before I bought them (in the store). Is there an expiration date to nutrients and these opened bottles are f....up my grow?

 

[ZenArcade]

Most have a shelf life of a few years, organic is a different story though, if it was opened i would try to use it within a few months.... I think you're right though, could be the nutes.

yes nutes can and will expire, organics MUCH faster than chems.

if you are <6 months you should be totally fine, <1 year and you might have issues, if organic and over 1 year old? ehhhh I'd try some fresh stuff out and see what happens...

you've got the temps down, so long as they are CONSTANTLY that temp, cant take the temp in the morning and then all thru the day its 80... just checking to make sure because 68 F is just about perfect for DWC. with good air you should have no root rot in those buckets...

are you sure its root rot and not just a buildup of nutes on the roots?

I dont know if organic is what you are trying to do, but you could try out some chem nutes and see what happens.

I used to run DWC, not any more, but while I was, I used General Hydroponics and the Lucas formula, super simple, just two bottles of nutes needed for most stuff.

if you are pumping in a LOT of air, it will adjust the temp of the water to whatever the air temp is, i.e. you push 80 degree air thru 68 degree water, its gonna warm up fast...

might this be an issue? or are your ambient temps good too?

If it is organic, I find that most Organic liquid nutes that come with directions for hydro use should mostly be used in drain to waste applications. If you're gonna recirculate a liquid organic nute or any nute that has mostly organic ingredients, i would watch it really close, change it out frequently, and keep my temps below 65f if possible. Is Bio Nova the new organic line made by GH?

I've started using the bottle right away when I bought it. Dont know how long the bottle has been on the shelf of the store...opened.

 

[ZenArcade]

Good luck, DWC can really yield some weed!

 

[hannuhuu]

yes my ambient temp is also around 20-25c. Have to buy another nutes
next week. If it's the nutes causing this don't buy anything from store called Pispalan Palmu in Finland they f...up your grows. I think they are mixing their own nutes in the BN bottles.

 

[ZenArcade]

If you can get GH nutes where you are, that would be your easiest, safest bet.

YES I know Allready my monstercropped plants yielded aroud 50-60 grams of leaf at 3-4weeks of vegging. It was so big disapointment notice the root rot. Heres a picture of the plant at two weeks http://www.icmag.com/ic/picture.php?albumid=13749&pictureid=299505

We got Advanced Hydroponics and Bio Nova here. It sucks to have only
two growshops in my country.

 

[ourcee]

finland? as in near the dutch?

you've got more than two... why not mail order some?

hell the GH stuff is cheap.

 

[hannuhuu]

We've had some problems with customs officers opening the packages and then the police comes to take away your plants. I dont even dare to mailorder within my own country.

I think I have to order it from online. Any suggestions where this GH is cheap and has reliable shipping in europe?
But thanks for now....

Due to low availability I would think you want a system that grows fast using the least amount of nutrients. Most of the products in my journal should pass customs as they are used for any type of hydroponic gardening or for reptile owners

 

[hannuhuu]

Just ordered Andvanced Nutrients from UK. Just have to hope there's no police behind my door in few months.

Root rot is environmental, the nutes can contribute, but will not be the cause. I do not do celcius, temps over 75f, will cause root rot. Any leaf or organic matter will help it start, in the water.

Rrot is simple to remove in veg, start bloom clean and it helps. Take a bucket of tap water with chlorine in it and dunk the roots several times. Gently massage the roots underwater with clean hands, to remove any color or matter. This works like a charm, good luck. get temps down.

It truly was the nutrients. I have two bottles of bn aqua, I compared the liquids inside and other was light green (this should be normal?) and other was BROWN! The growshop ripped me off with shitty nutrients. Finnish growers do not support Pispalan Palmu, they rip you off. to everyone who helped me with this problem, I learned alot. You have to pay your dues and I just did .

Oh, one more question. What colour should be pk 13+14 and additives you can use with hydro? I have an itch that these nutrients are f...up also.

 

[Haps]

Some nutes are brown, do not confuse nute color clinging to the roots and root rot, they are different. The heat is your first issue to fix.

Did you read my previous post the compared bottles were the same bio nova nft aqua. It can't be two different colour liquids. And if I have solution temperature so low I dont even need a meter to test it, believe me

Ok, did a temperature check for you Haps. My solution temp is below 70f, that is around 20celsius. Its about the same as my ambient temp.
