Hope to get some feedback about nutrition :
After 1 plant developed a small brown tip, I started feeding. A total of 116.6 liters of water goes into my system. The feeding schedule says that you should give 4 ml of root juice per liter of water. So: 116.6 x 4 = 466 in total for week 1. So, 466/7 = 66.5 ml per day.
Despite this, the differences in root growth per container seem very different. 1 bin was so far behind that I changed them. However, after 1 day a brown mass developed in the roots. The others are still nice and white. Is this already the bereft root rot?
I've made some pictures and a video. The first plant in the video was first in the container of the third plant in the video.
EC value = 0.6
PH = 6.6
Update 3-5 : After adding more air, problem solved.
Need to keep an eye on plant #3. I've put sticks on top of the startblock. 1 stick is plant #1 etc.
Plant 3 is behind the rest. Root development also differs from the rest. Instead of a long (about 50 cm) long carrot, they are a few short (10/15 cm).
The plant is also significantly smaller than the rest.
Can't do much now so, let's hope and see she can catch up.
Can my fellow growers take a look at my root growth in mij DWC system? I've addes pictures and video in week 2 of my growreport. I do use a waterchiller at about 19 ºC
Hello.. Hope you are well.. I think wots happened is ur nutes av just built up around the root system.. Seems a bit like alot of juice for small plants atm.. Maybe try dropping ur ph to bout 6.0 if possible.. Over nxt frw days she shud carry on developing roots n growth so u'll know cuz she'll slow down growing.. I dont think its root rot tbh.. Give her a few days.. If ur resivour isn't above 20°c she shud b fine n u wudnt need a chiller.. Stay safe n gud luck.. 👍🍀
The plants in my system do not
do not grow up evenly and brown deposits on the leaves. Water temp was high 21 degrees and has now been lowered to 19. Ph 5.7 and EC 0.6.
Nutrition: No nutrition because I thought brown leaves could mean overfeeding. I've added 4 pictures #somethi
I think I found the solution : water temperature. It was about 21,8 °C. Brought it back to 19ich and, well, look at the result in my media (video). Thanks for thinking along @Shagrath.
Because my nutrition order is delayed, it's just water for now. They look oke to me. Hope to get my nutrition today! 2 weeks later.
I found out, my DWC system wasn't stable. This caused to much difference in temp/EC and PH. Now I"m sure I found the solution but, do you think I need to start over? 2 look very very bad. See pictures. I made 1 picture of each plant in te last serie. See the difference.
After 2 difficult weeks at the beginning I have my dwc system under control. However, the plants have suffered a significant blow. Asked last week if I should start again but continue. Now again the same question. Last picture shows 1 week progression.
Hi there!
Now that they started to flower you want to give them as little stress as possible to help them make good flowers. defoliatiom is okay as long as you dont take too much.
When the stretch is over at arpund week two or threw then is the time to switch to bloom nutes!
Liquid seaweed is good flowering booster!
Why does this plant bloom so slowly. It also remains very low (30 cm vs 60 cm). It cannot be light spectrum unless a panel is defective. See last photos in my gallery. All other plants are loaded with buds.
Hello,
I'd say give it a little longer to see if it will start putting out bud sites and pistils. Maybe its internal clock is off and will flower late..
Otherwise it is possible to get a photo period in with an autoflower batch. If the plant doesn't start flowering soon you may need to initiate a 12/12 cycle to it and see if starts to show bud sites, then it'll be pretty obvious that this plant will need to be given the 12 hours of darkness each day if you have somewhere it can go.
Help! One of my plants seems to be out of order. EC 1.6 PH 6.1 (after feeding.) Do you have an idea? I'm pretty desperate. Photo was taken in the night hours. EC and PH are stable. Water temp 21°C (I might go lower)
Humidity : 63%
Temp : 24.3
To much airbubbels?
I have my Class 1 license and I learned that in a classroom but when it came time to driving... Driving was very different then actual theory and practice.. Your logic and reason maybe sound Gmslave but there is a lot more going on to Cannabis. I got my Degree from being CRAZY ha ha. you do you friend that's all we can do right?? Honestly I appreciate when someone peeks my interest. But I don't like to argue so I'm just gonna leave this....
Like I'm autistic so I wanna just keep going on and on.. to try to explain my point... But I seriously can't stress this enough... lots of people don't use water chillers... Me included lol.
or if they know they have bacteria problems with there water... Water is actual a fairly clean and stable growing medium.. Why do you think it makes for such great growing...
Great help my friends. I also suspected a clumping of the nutrients. I also noticed that there were fewer air bubbles in this tank. This made it easier for the nutrients to clump together. So I increased the air supply to that one hose to blow the roots clean. The result was already visible after a few hours, see last photos. Thank you very much for your help.
@Wollywinkah, well, different plants, dfferent phenotypes, different places in the grow room different microclimates, growth rate is determined mostly by the environment (VPD actually, have you heard about this?) so small changes in the climate because the plants are not at exactly the same spot will mean that on average one will simply grow more than the other... if you do that scissors thing on the small one it will overtake the big one very quickly , see for yourself 🚀
@CRiSPrGrow, About the roots: Can you say something about the difference in development in terms of root growth? Plant 3 (3 sticks in the starting block) has clearly less long roots but thicker. However, the plant itself is a lot smaller than the rest. I've added some photo's.
@CRiSPrGrow, Hi! Yeah, I figured it out. It was clumped nutritions. Increasing the air did the job. Roots look clean now but I stopped giving them nutritions. If it's all good today, I'll add en new dose of nutritions at the end of the day. Looks good now!
same question as last week: does it still make sense to continue this grow? See last photos to see the backlog. Last advise was : wait a week. Doesn't look as much progress to me.
So, one week up and running and there is so much going on. The roots grew almost 30cm. So, in one week from seed to this, amazing.
Started giving them root juice. Because I have a 116 liter system, I need to give them 464 ml in 7 days so 66 ml per day.
I also had one who grew a very small root in the startblock but in the end, didn't make it. You can take a look at the photo's below.
I keep my PH at 6,5. EC isn't doing that much but that's oke I guess.
For the little knowledge I have, things are looking good.
Keeping temperature during day at max 27 ºC and humidity around 50%. During night I'll let the temperature at 19 ºC minimum.
We had very sunny days this week and, it was a good test for the room if it could take the temperature stable. I had some worries about that but everything worked perfectly.
