Photos for bro!!! //GhettoStyle

Si les derniers paramètres inchangé sont: L'eau, La lumière, et Le pH-mètre ? Je vote pour le Ph-métre.

yes, but those balls that were added to the baskets before, I have already thrown them out! And now I have new clay balls!!!

oh oui, mais dans les paniers, ce sont les mêmes billes?

dear friends!! I don't have a system with clay balls anymore!! I'm already using DWC!!!

si tu as tous changé ou testé. Essaie de les changer les billes d'argiles pour voir. Ca parait idiot et j'y connait rien en hydro mais ca parait un paramètre facile a changer.

the fact that there are clay balls blooming somewhere! and algae formed, I know all this and it doesn't really affect the plants in any way!! but the fact that I have the same problem everywhere in all photos of plants seems to be the same!! And I ask you to help me identify this problem!

So if I'm correct in what I see here, all four plants are using the same reservoir, yes? You have some photos that show what seems to be a top-water drip system as well as a bucket... and I think this is where the problem is - at least it's where I would start. The drip system is probably giving those plants nutes from the top and the very dark, almost black clay pebbles indicate to me that a fungus is growing there... which would make sense if your top-water drip has nutes in it. The reason you need to keep all light out of your bucket is so fungus doesn't grow down below in your roots - but if it's growing up top and you're watering from the top, it's sending that fungus down inside your buckets and reservoir. It's the only thing that is making sense to me. You want to top water with ONLY plain, pH'd water, not with nutes. And once the roots hit the water in the buckets, you don't have to top water any more. What I do for my DWC is to prepare the bucket reservoir with root enhancers and a VERY little nute solution (EC of .02-.04) so that when the roots hit the water, they're getting a little bit to eat and something to help the roots grow well. Before the roots hit the water which is usually about the end of the 1st week from germination, I hand-water about 1/4 cup of plain water through the pebbles once or twice a day around the stem (not up next to it) - that's it. I also start my seeds in Root Riot as opposed to rock wool and they, too, give a good initial environment for those roots to grow. So those are my thoughts here.. I have no idea whether I'm right or not but nothing else is making any sense to me... you've got VERY dark, almost black clay pebbles and that is not natural.. Good luck.

1) No more tap water, if you're using it. Go with demineralized water or osmotic water with EC 0; 2) After the first 15 days of life, avoid wetting the expanded clay in any way, it must always remain dry; 3) Buy a chemical PH tester, much better; 4) For anything else, check out my diaries, they're quite detailed, and the diaries of @SwissKush too.

keeping it short, which is unusual for me: Hydroton sucks, AN sucks... though plenty of ppl make it work, so it is possible. Just don't follow instructions for AN, lol, and good luck with it. overfed lockout.. maybe some pH swings.. AN is properly pH-buffered, imho. A good hydro nute's pH won't drift or will be more resistant to it than AN. If you can calculate ppms try to be near: N/P/K 120-140 45-60 180-210 Ca / Mg / S - I have hard water. You my need higher amounts of these than i do. 100+ 85+ 100+ something near 650-750ppm. These ratios at 6.0 pH will be great. Other factors will impact what you can feed, but this will be a good starting point. if using a tDS pen, that is on the 500-scale / "Hanna" brand, but better to calculate ppm from guaranteed analysis lables or use an online calculator at manic botanix. the ratio and concentration of these elements is supremely important, and more so for hydro. 6-6.5pH is fine. I don't know why ppl are so adamant about 5.5-5.8pH for hydro.. all that does is put you dangerously close to locking out some of the nutes. 6.0 is safer. Nothing wrong with 6.5 that a small adjustment or two can't make work, either. buy jack's nutes and you won't have to pH adjust anything, ever. a real AG company and not some esoteric "pot" brand nonsense.

my pH pen is working properly! I calibrate it once a month!!!

I do kinda agree with Aldo90. Hydroponic growing is really too advanced for most beginners... Maybe start and complete a quick grow in soil and get good at identifying plant issues and dealing with them before adding so many other potential variables to the equation.

I'm betting your pH is all over the place, because I'm seeing signs of all kinds of deficiencies, and any good nutrient solution should prevent that. Use test strips to keep your pen honest...and be aware that if you are using city tap water, huge fluctuations can occur...never assume it is the same as the last time you checked it.

You have some serious nutrient issues. This could be caused by actual excess or deficiency in your res/feeds. But I feel like it’s very possible it’s a pH issue. Maybe your pen is outta whack, sometimes not being calibrated or just over time they lose effectiveness. Maybe you’re not taking pH at all. There’s a lot of possibilities but you’ve got lots of signs of the plants not getting what it needs and that could be in the actual feed or because it’s not available to it with the pH being off. I don’t believe it’s an aeration issue. I can see in several of the DWC pics that you have plenty of air going. Common misconception is that they need some crazy amount of air dissolved in the water. It’s really not that much more than standing water. I’ve seen the math done on it. This is my 2 cents from a dude who’s run DWC probably a dozen cycles.

Light • Clone and seedling stage: 5,000–7,000 lux • Vegetative stage: 15,000–50,000 lux • Flowering stage: 45,000–65,000 lux Ph For your DWC, the ideal pH is around 5.8 ( 5.5-6.5 is ok) Water temp 18c min - 25c max limit then you will start getting issues Perfect EC level for cannabis plants is around 0.5-0.8 until around 13/15 days after germinating. This should be progressively increased to 1.1 towards the end of the growth period. During the bloom stage you’ll need to increase this, as your plants will need more nutrients. You should keep the EC between 1.2 and 1.5, keeping it there until the fattening period, where you should increase it to 1.8/2.1 – this is the highest it should ever be.

You want to do dwc but are struggling. Running before you can walk. Learn the basics.

you look carefully at all the photos!!!

I think it's crazy!! the fact that I have a shortage of bubbles!)) I'm telling you there are enough of them and I had the same problems if you didn't notice in aquafarm!! -- and there should be no bubbles at all)) so my problem is not related to what you are telling me!))

it seems there are few people here who can really help with advice!! Mostly they advise what I already know (((

no bro! there is enough air for a hiblow20 liter pump per minute for 5 pots!

If you follow correct nutes amount, pH level and good amount of light for me it looks like there was not enough air for the roots 99% sure. When I look at your pictures I can see there is no a lot of bubbles in the tank. You should have a mixture of medium and small bubbles for best results. Please see below my hydroponic diary and check the pictures. On week 7 you can see that the bubbles are everywhere and different sizes. growdiaries.com/diaries/107249-grow-journal-by-ilovegoodweed/week/585465 The solution would be to put 3-4 cylinder air stone 50x50mm per tank and get a good air pump like Hailea ACO-318 Air Compressor Pump or bigger. Make sure in first 1-2 weeks keep the water level higher so it slightly touches the plant pot and then keep lowering.

I don't want to do on the mix!! I want to do DWC!!!

Whatever you are growing in is the problem. Stop fuckin about and get some light mix soil and do it normally. Running before you can walk there mate clear as day.
