DWC whats wrong ?

[littlegrow]

so ive had these plants in the DWC for about 7 days today and using 2 air stones and growing them in hydroten, they have been growing well in PH adjusted water at about 5.8ph, i added some nuts the other day and tested and the water was still at 5.8ph so all is good i think anyway i come back after 2 days to find my leaves turning yellow and the ph at around 7.0 to 7.2 and the water is quite warm

so added some PH down today and the water is now back at 5.8 ish. the roots have started to come though, they were started in soil but i switched over to DWC a few days ago as i don't have any rooting gel or powder so i can't start any clones without powder

should i cut the yellow leaf off ?

what nutes are you using.. and premium water temp is 68 degrees F

You should drop your PH to about 5.2 for DWC. Let it drift back to about 6.0 and readjust. Because of the PH swing in DWC if you keep readjusting to 5.8 you will have to check your water more frequently, it will be above 6 in no time.

 

[kickinit1]

I would say 5.6 would be safer.. and let it rise to 6 before dropping it back down.. Add some silica. This will stabilize the PH not allowing it to rise so much

Be patient before you do anything.

As long as the dirt/rootball isn't soaking wet, and the roots are poking through, your alright.

The leaves yellowing are likely because the roots haven't developed enough after transplant to start feeding the plant at the rate it needs under the amount of light you have.


And if your ph is rising that fast I can only imagine your using tap water with high alkalinity, to amend that, before you add any nutrients, bring the ph of your tap down to 4.2 and stabalized it there.

After you neutralize the alkalinity by acid, anyone works, you can add your nutrients.


Or just get an ro if your going hydro.

hey guys, Yea Architect, im using tap water which is about 7.0 so gotta use PH down. today i cleaned the DWC tub out and put fresh water in and did a ph check and was at 7.0 so i used ph down to bring it down to about 5.6 as thats all my chart goes down to as i don't have a proper ph tester yet. the roots are still inside the net pot, should i gentally push them though the netpot holes ?

 

[TheArchitect]

No, just water from the top till roots touch water.

 

[cravin morehead]

good advice here. get those res temps down to under 70*f at least. 68*f is ideal. if not, root rot will set in...

never adjust you water ph before nutes
fill your res so it covers a half inch of netpot,dont play with the roots
its bs about rr 70f



rez temps 75
lucas formula modified ph at 6 let it drift.my well water is superhard ph of over 8 no ro used

ok, ok, root rot and other bad shit can grow in your reservoir with warm temps. not always, but they can and could become problems

 

[littlegrow]

so whats best way of keeping the water cold or cool in the res ?

 

[cravin morehead]

get a chiller.

 

[kickinit1]

keep your room no hotter than 75 and your water should stay no hotter than 70.. maybe pull the hot air out of the top of your room if not doing so already. Oh and you can also try to hide that black plastic like you did on top.. Black material absorbs heat =)

With a name little grow I don't think ur using recirculating only pump in ur system is for air stoned so chiller is overkill freeze a few 2 liter soda bottles and droppem In ya res .... Now if u gonna do alot of lights multi buckets a chiller is a must.... What type of air. Pump u using air stones???? Avoid root rot is easy if u avoid organics and run a simple sterile Rez I've had temps in mid higher 70s no prob not that I reccomend that though a shot of h2o2 works wonders to... Lots of things cuz root rot just do ya homework to make sure ya don't got nuthin stupid like light leaks in ya buckets and keep ya mix simple and plen of air bubbles ya gonna be fine enjoy growin.... I ph my shit all the way down to 5.2 and let It drift up to 6.2 in veg plants like the lower ph for me atleast flower 5.6 Neway good luck

Could you possibly give me a reason to not ,in this case, adjust my waters ph first?


Have you ever heard of acid injection to neutralize carbonates?

One reason not to adjust you PH first...
Because your nutrients (any nutrients) will change your PH

Why adjust your PH twice?

 

[TheArchitect]

Hey bud, before you put your foot further into your mouth, maybe look up how you nuetralize carbonates using acid injection.

 

[kickinit1]

okay pal, i am somewhat familiar with the process, and as i understand acid injection is to neutralize the water. Meaning bring it to a neutral PH of 7.0. He stated that his water is already at 7.0 right out of the tap. What could be more neutral than that? What am i missing? Please educate me on this if i am clearly not understanding your point

I don't see the difference of PH adjusting and neutralizing carbonates

dont know or care ,an ro system is the way to go and of course a chiller but i do fine without either

 

[stoney917]

It's pretty simple .... Ppl over complicate things ad get water mix nutes in ur ph should go down as add things unless its organic certaithings dont shiw up ppms .... But basic is so from 7 after adding nutes itll drop to 6 then add ph down if even needed a good mix can drop u dead on ya spot then depending on how much they drinking top up with ph'd water or some more mix.... Ro can be very important when dialing shit in unless u lucky to have great water it's really a must have for some/most but a few lucky ppl get away fine.....
