this is my first grow and they dont look right to me
Looks like they are stressing a little.
I've had seedlings look like that (light and crinkled) and then come around.
Sometimes they can be temperamental early on.
Keep an eye on the new growth.
I'm not a hydro guy so I can't give you advice there.
My limited knowledge leads to following questions of deduction:
1. Any heat stress issues?
2. Root temp issues?
3. Water levels (roots shouldn't be submerged)
4. Ph strength (shouldn't be using full strength yet)
If all these are on point then no idea, hopefully some experiences hydro growers can help
Those look sick. Find the problem or scrap this grow
thank you for the replies. let me give some more information.
the temps are between 72-75 during the day and 65-67 at night. the reservoir stays at a steady 67 degrees. i keep the ph at 5.8 and it usually goes to 5.9 or 6.0 over night. the humidity is between 50-60%. im currently using the technaflora bundle for nutrients at quarter strength (480ppm). this is a rdwc setup so the roots are always submerged in water. the strain is feminized cookie wreck from cannaventure and they are all from seed and popped on november 10th.
i did a ton of research and spent a lot of money so i could have a succesful grow. from everything i have read, i have given them an ideal growing enviroment with little to no fluctuations.
ive had a lot of new growth since my original post but it still looks weird. should i really scrap the grow?
Your fucking something up.I kill DWC man and please post more details so i can help.Your not doing something right.Plants look overwatered which means in DWC they are not geting enough oxyegen.give more details on setup,water quality,etc
I wouldn't say it's scrap and start again time but you're going to need to remedy this in the next two weeks I'd say.
From what you have provided ranges are all good. (altho I'm no pro)
Leads me to think about levels of oxygen in your reservoirs, you got air pump and stones? Is the water bubbling?
Yes roots will sit in water but shouldn't be submerged fully, check your water levels.
Otherwise, CO2, you changing air enough with intake / outtake?
If one plant is sick in a dwc... they will all eventually be sick. They'e sharing the same pool of water. Ive ran dwc before. More hassle than reward if you ask me. Clogged feeder lines. Risk of powder meldew is greater imo. And if you have one sickly plant... chances are there is more to follow. It looks like you got a nice setup... the plants tho are on their last days unfortunately.
Note. Your rooting system for dwc should NOT be fully submerged under water. Even with air stones in each bucket. You should have no more than half that root system underwater. And that' pushing it imo
this is the 6 site bubble flow buckets from supercloset. it didnt come with an air stone for the reservoir but each individual bucket has one. i had a spare air stone and put it in the reservoir this morning. the water will always sit up to the return line and i dont see a way to change that. i have a 6 inch fan pulling hot air out of the tent but no active intake. i have a window fan that pumps fresh air into the room the tent is in. i am using very hard tap water at 240ppm. i will go get an ro filter today if you think that could be the problem. the plants have looked like this from week 1 and are getting bigger everyday.
You don' know what your talking about.roots out of water are subject to pithium because the water can' keep them cool.the purpose of water culture is to submerge your roots.if you want a good case of root rot or algae let your roots hang out of the net pots
And this is why you shouldnt even be giving advice on it.stick with dirt bagging man.leave the real advice to people who have actually mastered it
DWC when done right kicks the shit out of anything else.no hassle,no watering plats,no guess work.hard to dial in but once you do nothing comes close.
1st don't give up. Everybody fucks up it can't be helped. Besides if you give up now you'll just end up making the same mistakes later... It looks like the plants aren't receiving something. The lack of roots is normally caused by a lack of oxygen in a hydro system. Touching the roots can also shock the plants and cause root lost. If you haven't touched the roots I think your plants are sitting kinda low in the net pots for a system of that design. You want the base of the plant to be above the water line. If its not possible to lower the water level increasing the amount of oxygen you're pumping should help. Also are you sure you have your system set up right? The return port should be at the bottom of I'm not mistaken. If that's not possible what I would do is unplug the return pump and turn each individual site into an independent dwc, lower the water level that way until the root system is way more established and then revisit the recirculation aspect. But again that's only if it isn't possible to lower the water level
Next your ph shouldn't be rising that fast. Which means your municipal water isn't clean enough, algae, or you have a light leak. I would address them all honestly. Feel the side walls of the system and see if anything feels slippery. If so algae is present and enjoy cleaning out your reservoir and buckets. If not go and get some black plastic sheeting and drape it over your buckets. This is normally a problem for people that use normal containers in their system like Wal-Mart totes and it shouldn't be a problem for you since yours are specialized but the fix is so simple and it will help rule out a potential cause of your problem. I'm thinking light could be seeping in through your clay pellets allowing things to grow in your water. Next filter your water or filter it better then allow it to sit for a day or so before you mix your nutrients. Allowing it to sit will give some of the dissolve gasses a chance to evaporate off ( like chlorine) you'll see small bubbles in it when the process starts. Then increase your ph to 6.0, increase your day temps to 78-80 and your nigh temps to 72-74, and increase your nutes to 1/2 strength. That should correct any ph,nutrient def, temp, algae/ bacterium,or hard water issues .
He can lower the water level.the water is to high.it' above the plant crown so it took them a while but they will start to straighten out now.the water return line should be on top but doesnt have to be below the water.he has the pump hooked up backwards.it' supposed to pull from the bottom of the buckets and dump back in from the top.once he gets it right he can lower the water level to about an inch below the top square holes in the net pots.
His pumps backwards lol
And I know it sounds like a lot but if anything I've said sounds like Bullshit the others would call it out
Why so many people who don' even run hydro give so much shitty advice on these forums is beyond me.dwc recirculating always pulls from the bottoms and drains back to a epi bucket.also 6.0 is to high in hydro.he will have phosphorus issues and calcium lockout.5.6 to 5.8 is ideal.5.8 is the sweet spot.also rising pH is ok.it will swing upwards and that' good.a falling pH is bad.
Here' is 2 week old cannaventure ghost OG in a recirculating dwc I built.
His system is shit.I would 86 the 3/4 inch pipe on the bottom and go to 1and a 1/4 inch pipe.there isn' enough circulation using that little hose at the bottom of the buckets.plus those net pots are way to big for those size buckets.here is my setup using parts from home Depot that cost me less than 200 for everything.
Oh miniaure ass project grows
