PPM rises past desired level

[dudeoflife]

One more thing--- what is the origin of this plant? From seed? From clone?

Those funky 3 leafers are quite common in DWC. I took a closer look at the pic. Yes, those leaves are pointy!

I've gotten similar looking plants from taking clones off of flowering plants, too.

Welcome to DWC!

righto n man! i am installing 400 watt mh right now. plant is from clone. i may have got the idea for subtle changes from dealing with aquariums and such. thankyou!

 

[onthedl0008]

Absolutely! I know I'm a day late and a dollar short, but

I have seen the best gains after letting my plants to their thang, and coming back to a whole bunch of buckets with less than a gallon of water left.... Never measured the ph or ppm, the plants looked too damn good to really care.

Really though, your ppm are skyrocketing, but your plants look great. And you are worried. What gives?

Great post man. Ur absolutely rite. Once i set-up a bucket and everything stableizes it really doesnt matter. Nothing does seem to give because ur letting plants do there thing. Ive ran certain strains into 1800ppm range in the third week of veg as well as past 2000ppm in flower by allowing my water levels to lower as indicated and they seem to love me for it. I was basicly giveing general rules of thumb to grow by i guess more for safety for new growers just to get the style down.

Hell yeah! That's could DEFINITELY the origin of that ph myth.

You'll see over the course of this grow that is indeed not a fish

How's that for advice-- Do NOTHING. lol.

Go through my posts. That's about half of my answers.

I doubt you will come across too many grow techs, let alone the owner of a nutrient company (me!) that tells ya to do nothing half the time!

so ppm can be much higher in hydro than in soil? im usto running around 300-400 early veg...600-800 late veg....900-1200 flower. can anyone give me guidelines for hydro?

Absolutely. Soil plants go bonkers (in a bad way) if the ppm goes above 1000 ppm, generally. That's because you're feeding the soil. At least that's what you're supposed to think....

Soil roots then do their part to assimilate the elements.

DWC plants have water roots. So, in DWC, or hydroponics in general, you are feeding the plant.

You raise the ppm over the course of the grow to raise the osmotic pressure, as the size of the plant increases. You are doing the work of what soil roots do in soil plants.

Generally speaking.

 

[dudeoflife]

And your ppm schedule is on point.

Again, change nothing.

Do nothing lol.

A real good feed schedule i have stuck to in DWC is the following And real simple.
Sativa dominant strains can be pushed to 1600 in VEG ( Depending on the length of VEG ) and maxxed at 1800 in Flower with no problems.
Indica dominant strains or hybrids for that matter or just strains with great genetics in general could and should be pushed to the fullest extreme. I have maxxed Good genetics to 1800ppm in VEG and beyond 2000ppm in flower but keep in mind all strains cannot and will not take heavy feeding.
All this is based on a 4 week VEG max.
I feed my res 1-300 ppm on set-up.
Once my PH starts balancing and i get roots in the water i begin upping my ppm about 100 per day or every other day depending on the reaction of the plants. Sometimes it takes 4 days to week for them to get acclimated until they really want to eat and u notice the huge growth explosions.
But dude of life is right. Just keep things proper and let them rip. Afterall these are just weeds and this is a very simple style of hydro to grow in.. Soak it all in and try to apply it to ur grow. Most of the time it is best to just do nothing like the pros say dont over worry ur grow the plants will grow themselves. The pros have passed down enuff info to us to allow us to just sit back and grow jungles with minimal effort. Just apply it.
Ur doing good.
Peace

Thanks bro...good information.

No problem and i think alot of the undercurling thats happening on ur leaves is do to inadequate Lighting due to the size of the plant. And possibly heat issues. Id lean more towards the lighting tho. I do believe that feeding and lighting go hand in hand. And the plant in the PIC is in much need of the HID.
Put the 400 up.
Keep ur water level proper.
Keep ur PH on point.
Like i said keep at it sounds like u got a real good feel for growing.
Lol i once heard and keeping it REAL simple " Haveing a green thumb really helps".
Haha. Peace hope it helps man.

 

[aeviaanah]

got the 400 up already ready to take dwc to the next level. thanks everyone.

 

[aeviaanah]

reduced down to 4 airstones and i will raise water level in the mornin....i think 600-800 ppm is a good range for this size plant...will see how she reacts.

 

[aeviaanah]

stay tuned i will post some pics up tomorrow

Growing a deep purple in a 5 gal dwc....there is about 2 gallons of nutrient water mixed to 800 ppm. After a week or so i get ready to change nutrient solution and ppm has raised to around 1600 or so. Curious as to what may be causing this? Phd water in at 5.5 comes out around 5.3. Plant seems to be absorbing nutrients and is growing quit fast. I have around 8 large airstones pumping air into reservoir. Im adding supernatural brand grow 20-20-20...to around 600 ppm...a few additives like seaweed extract, root zone conditioner, and silica from dutch masters. Plant could use more light...only using two low watt cfl bulbs, just to get by till i set up 400 mh.

leaves are tending to look abnormally pointy and long...and are slightly disfigured when small. nice dark green, no purple hue, burnt tips or leaf curl. something is off as i have grown this strain in soil. plant has nice healthy rootball no slime or blackening of any sort.

resevoir water is ambient with room temperature...70-75 deg.

could be dealing with too much nutrients per the amount of light she is receiving?

why are ppm drifting up and ph drifting down, shouldnt it be opposite? i just phd water in at 5.7, this way if ph drop becomes a trend it will drop to around 5.5.

This is what I've noticed. You're doing DWC and using Supernatural Brand 20-20-20. You're using Gro Terra right? That's used in soil or soilless mix. You should be using Gro Aqua in DWC. I do 5 gallon DWC also and I have used the Gro Aqua, Bloom Aqua, and Superboost. Go get some new nutes and you'll have no issues. I ran a whole grow from veg through flower and never have ppm or ph issues. In fact I've never even had to adjust ph ever throughout the grow. It was buffered perfectly between 5.7 and 5.9. Just like you I also only put 2 gallons of nute mix into the bucket. You probably use the large net pots like me. I'm using the 10" net pots and veg under 600 watt MH and flower under a dual bulb reflector with one 600 watt Hortilux HPS and one 400 watt Hortilux blue so I get dual spectrum. I've only run one plant though cause I only had enough nutes for 1 grow. My hydro store gave these nutes as samples to try out. The results were really good and very stable. I might switch to Supernatural after I'm done with my House and Garden line. Not sure on how good the yield is though cause I used these nutes on a small yielding/growth plant so I could squeeze it in to a small area in the middle of my tent and not get in the way of my 4 large plants. I vegged it for 2 weeks and flowered it at 6-8 inches and it yielded 1.5 oz. at 18" tall. I let it grow single stalk with no training at all. Trimmed out the bottom and just flowered the top 2/3 of the plant. Now I'm really curious on what it would do on my large high yielding plants.

Thanks for the information! Ive heard lots of good stuff bout house and garden....you satisfied with them? This is odd, I thought this was a hydro nutrient as well as soil and soiless. I feel dumb, lol. I went and looked at the package and sure as hell, no hydro on there anywhere. This is where the ph fluctuation is coming from i bet, thanks for actually taking the time to read and understand what was going on. Ill post a picture of how the plant is doing now. After installing 400mh, she just took off! I just measured ph and ppm...ph=4.9 and ppm=850. Ph is lowering and ppm is staying the same. This explains why i keep having to raise ph. How well does hydro organics perform?

No problem bro. Glad to help. Your plant is looking pretty good but you see how the leaves and branches are growing kinda funky? That's because of the 20-20-20 NPK. That NPK is not right for hydro. Go get the Gro Aqua and Bloom Aqua and you'll never have to adjust ph. Just top off with ph water or even right off the tap. I've done it before when I tested out those nutes and the ph still seems to buffer within range. My tap water ph is around 7.4. I don't use any organics in hydro. I stay away from any organics cause it will slime your roots and cause you a shit load of problems. It happened to me once and never again. Currently I'm using House and Garden Aqua Flakes A and B, roots excelurator, drip clean, multi zen, bud xl, top booster, shooting powder and Great White from Plant Success. When I'm done with these nutes I might switch to Supernatural because of the ease of use and the ph buffer but if it doesn't give me 5 oz. or more per plant I'm switching back to House and Garden.

 

[onthedl0008]

Dam nice catch WS. Yea AV if u want to run organics like i ALWAYS have in DWC. Get some Botanicaire Pro Series. I got nothing to gain by endorsing the product only that i have always used it growing DWC along with the CalMag supplement later in flower. Probably better nutes out there IDK n i dont care they always worked for me. Never had any probs such as burning, funk in the res, none of it and i literally dump my nutes directly into the res when adding them no mixing i guess like the synthetic nutes ive been checking out in coco. My whole entire nute line-up consists on the pro series veg and flower. And calmag. Real simple. Peace.

Ive asked a few people about the funky look to the leaves...some acted as if it was normal. I knew it wasnt, thanks for the assurance. I discontinued Supernatural lineup...had a sample of botanicare cn17 grow for hydroponics so i decided to use it. I mixed with calmag, humic acid and adjusted ph....900ppm. I also treated her with some azatrol...hope i dont stress her out too much.

I think i am going to do organic soil and synthetic hydro. is botanicares calmag organic?
