Whats wrong with my plant

I have a white widow, barney's farm, growing in coco coir and perlite mix 60/40 using vitalink A+B and calmag only... using philzon 1000w LED she's about to flower but her leaves are turning nasty... pls see photo... any help is appreciated... P.s I've flushed her as her EC out was a massive 3.2 she's down to 1.3 as of last night and going to flush 1 more time tonight... from Hydroponics / Aeroponics read more

Water PH

I have well water that is acidic. 5.2ph today. My water also has a fairly low alkalinity @ 23.3 ppm. i understand 20ppm-200ppm is normal. (I had the water tested by a lab) From what I understand, alkalinity has to do with waters ability to buffer ph. I mixed up some maxibloom today @60grams/15gal to give me 1.1ec in my reservoir and this dropped the ph to 3.94! It took 43ml of GH PH UP to raise the ph to 6.0. PH UP is potassium carbonate so I would like to know if this 43ml of ph up... Water PH from Hydroponics / Aeroponics read more

pump/hose for oxypot4 water changes

Just wondering if there are any off the shelf solutions for this? it's a bigg ol' tank so I was thinking I could rigg up a hose from the tent room to the bathroom with a pump like THIS for occasional refills/drains, but I'd need to give the pump it's own little power supply so I can wrap the whole thing up and out of the way when I don't need it.

Hanna gro line meter

I’ve had a Hanna instruments groline monitor for my hydroponics setup and it did great for a while and now it goes a few days and then shows my ph has dropped to 4.34 and won’t change the temp amd ppm will change but stuck on ph. I cleaned it in the cleaning solution and then let it sit in the storage solution for 3 days and it worked when I took it out rinsed and tried but this morning was back at 4.34 from Hydroponics / Aeroponics read more

Nutrient Uptake

Hey Gang! Quick question about nutrient uptake in DWC: Does anyone know if plants consume the nutrient solution as a whole, or are some nutrients consumed faster than others. For example, if a plant consumes a gallon of water, would it also consume 100% of the total dissolved solids in that gallon? Or can it consume something like nitrogen faster than magnesium and over time throwing off the concentration of nutrients in the solution. I haven’t been able to find any information on this...

No matter what I do the ph in my 1 DWC rez is 6.3

Title says it all and this never happened to me before. I've underfeed the plant or overfeed the plant a little in DWC and the rez is stuck at 6.3ph. I will use ph down to get it to 5.5-5.8 range and the next day its up to 6.3 again. What's going on?? On day 18 of flower, its been doing this since day 1 of flower. from Hydroponics / Aeroponics read more

Octopot, Air Injection Technology or Similar Systems

Hey Rollitup Community I'm an amateur hortaculturist and by that I mean I don't just like the study of cannabis I enjoy it as a subject generally. I was wondering if any body had used the octopot system or another version of a soil/dwc set up like the ones featured below.

Aeroponics - SCROG for the roots?

Hey everyone, New guy here. Been a long time grower (mostly rdwc) but am looking to get into aeroponics, and I've been making plans to build my own high pressure setup. Given the reasons why aeroponics works so well, I was wondering if it would be beneficial to put a small trellis in the bucket underneath the net pot to allow the roots to spread out and gain more exposure to the sprayers? When the root mass grows into a big ball, I could theoretically see some of the interior roots being... Aeroponics - SCROG for the roots? from Hydroponics / Aeroponics read more

Ok, I have been growing in soil for years and decided to try DWC. I have these beauties (6 of them in total), I don't have a proper tent available yet (I have a monster scrog flowering at the moment) and I'm gonna be away for 2 weeks, leaving in 2 weeks. While I admit that my arrangements are terrible, I'm comitted to making it work (somehow). This is my setup: Tent 1.2m X 1.2m (47"x47"). I m going to be able to set this tent up in exactly one week.

Switching to Hydroponics after many years in soil. A few questions.

Hello everyone, I'm about to change my setup to hydro. Right now I'm between DWC and the GHE Hydro System. I've got 3 tents, a 0,45mX0,45m for sprouting and early vegging. Then I ve got a 0.75mX0.75m with a 150W LED and a 250W HPS and another 1mX1m tent with a Spider Farmer SF4000 450W Led. 1. I usually prefer doing SCRoG for max yield and I would leave a plant vegging for at least 2 months in a 55 liter (12 gallon) fabric pot but I was going for 1 plant only.

Precipitation and clouding in nutrient?

As the title suggests I'm getting some problems with the nutrient. To begin with I was using canna ab with a few drops silica (with potassium added) to correct the ph I've since noticed some precipitate at the bottom of the reservoir.

Anyone here ever find that overfeeding PPM shows up as lock-out/deficiencies or excess symptoms?

For the first time in a while I am going to try and give my Plants exactly the amount they consume of nutrients and no more! in Flowering. This is what I try and do in Veg but for some reason since they drop their nutrient drawn down by over 30% after the flip, I have a hard time going that low i.e. 600 PPM This is looking to be around 600PPM and no-more. IS there any reason except maybe a smaller reservoir to go above the nutrient concentration that they are consuming in the exact ratio...

How concentrated to make Nutrient Solution in my 13 Gallon RDWC Reservoir for One big Plant?

I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...

Hydrofarm 5 gal ebb and grow help

I have a hydrofarm ebb and grow 5 gal system. The roots keep clogging the drain lines in early flower, I even trimmed the roots twice in veg. Any suggestions to solve this problem?

Dehumidifier Water & Cannabis

I find myself dumping about 1.5 gal of water a day from my dehumidifier. I decided to test it out with my meters & it tested at a PH of 5.7 and a ppm of only 4. I was thinking of using this water in my Res for my hydro system instead of dumping it. At 1.5 gal a day, thats about 42 gal a month Im just dumping out & it seems very wasteful.

Can plants drink water, but not nutrients

Just one noob question... Can plants in DWC drink water, but "not" nutrients? My previous plant drank a lot of water in late veg stage, I'm talking a gallon a day, but when I check ppm levels, they are pretty much the same as it was the day before. She was in high heat, high humidity environment under 300w mars hydro led. 82.5f to 91.4f 60 to 80% humidity If it can drink water but not "use" nutrients, then adding nutrients to the DWC reservoir without measuring is not recommended, as you...

Plain Water pH keeps rising. Please Help.

I use 26 ppm water for my DWC system. No nutes, no additives, nothing. pH is around 7.2. I lower the pH to 5.8-6.0 using Terra Aquatica pH down, and after like 3-4 hours, pH goes back to 7.0. I again add pH down and reach 5.8 pH, wait another 4-5 hours and it is still the same. I repeated at least 5-6 times. I changed the container several times, now I use a food grade container, and the result is still the same. Same happens if I add nutes as well. I lost many seedlings due to pH...

That is correct. Same EXACT ingredient as EZ Clone Clear Rez that sells for $20 a QT. Get your self a 1 lb bag of HTH Pool shock non PH buffered available online and most hardware stores (bought mine from Ace). Mix 1 GRAM (450 in the bag) per gallon of solution.

Anyone using canna coco nutrients??

I recently switched to canna coco nutes. Using tap water which comes out around 0.17- 0.2 EC. I was following the canna feeding chart since it seems pretty precise since you can adjust to your tap ec, rez size, etc... After adding the A/B, rhizo, cannazym and ph down my EC comes out between 1.7 to 1.9. This can't be right, or is it? I am even giving an ml or two less than canna recommends.

I have always grown with DWC. I normally just grow one monster plant in a 3x3 SCROG and have had some pretty awesome results.
