Technique
Transplanted Yelena into her new home, my first attempt at DWC...considering my luck with autos, this will be a learning experience with no expected yield, hence the cheap nutrients. For the life of me, I cannot get a stable pH, or at least not below 7. My only explanation is that I'm using vinegar to lower the pH and it's too weak an acid to keep the pH down amidst the bubbles from the air stone....just a guess, I've got some phosphoric acid (pH Down) on the way, hopefully that does the trick.
Mar 15 - sure enough, the phosphoric acid did the trick (after a short period of yo-yo-ing). pH is stable at 6.1, I know that's not perfect but I'm leaving it for now. Ppm on the other hand is going up...could be from withdrawing some water to lower the level to the bottom of the net pot but I'm just gonna swap out the reservoir tomorrow and start clean.
Nikita got tied down for the start of her LST, she's definitely growing faster than my first attempt at autos so at least I'm learning
Mar 16 - changed reservoir with fresh water and quarter strength nutrients, noticed 2 long root strands poking from the net pot - much success!

Misanthropestarted grow question 3 years ago
Yellowing tips appeared in the last 12 hours. I've been using a weak solution of root booster but I'm not sure if the discoloration is from nute burn or deficiency. Once roots are established I'm planning on putting her in a DWC

No chance for deficiency, I give just water until she is twice that size. it's either nutrient burn or the beginning of root rot.
Misanthropestarted grow question 3 years ago
I'm using 5% acetic acid (vinegar) to lower the pH but with 6 hours it's always back up to the original pH. A similar bucket with no aeration remains stable. Is it because I'm using a weak acid? Is there any way to buffer the solution to keep it in the desirable range?

Essig und Zitronensaft bleiben nicht lange stabil ! Der Ph steigt nach kurzer Zeit wieder an !
Misanthropestarted grow question 3 years ago
Roots are brown but don't feel slimy and give off no odour. New root growth is virgin white. Could it be discoloration from the nutrient solution or is it the dreaded root rot? pH is constant 5.9-6.1...I added 5mL/gallon hydrogen peroxide to be safe

Smell/Feel Them!
Rotten roots smell bad Feel slimy and soft.
Healthy roots smell not bad Feel plump and solid.

Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

hey there misanthrope, this is just your average nutrient burn you can tell by the burn on the tips. You have me worried about how you're talking about having 2.5 weeks left yet starting to flush soon. In hydro you wont need more than a day of plain water for a flush - that's kind of the point of hydro actually. Anyways, not a deficiency, try to reduce the nutrients by 0.5 or a bit less mL/L then work your way back up week on week . Hope this helps ! 🚀

This is a grow without a diary but the set up is the same as this except still in veg...had a 3 day power outage, seemed clean after but found mic. growth on the roots and air stone days later. Did res change and added h2o2 and after 3 days added NPK Bloom micr. Any1 seen this b4

Yes that's a bacterial infection. Its going to be a battle. Im assuming your in a DWC and not a RDWC.
Directly spray the roots with a 3% mixture once every 2-3 days and do a bucket change.
Every day add 2ml/L of h202 @3% to the bucket.
Keep your usual feeding since your using synthetic nutrients which can be used in a sterile environment
If you can add more air stones the more air the better.
Keep the air pumps outside your tent( or even in a fridge ) to keep water temps down.
If you can keep the water temp at 65F and never let it get above 70F( or below 63F).
Use frozen water bottles and have your bucket sit in a larger tote with water in it and keep that water at the correct temp which will keep your bucket water correct.
Get some white paper and place on the bucket top to block light from hitting the black bucket and heating it up.
If you have access to hydro guard that can help, But its organic so it will be killed by H202.
Good luck and Happy Growing

Keep your ph at 6.5
Fill the bucket with feed to the base of the basket, and let it drop.
You're over feeding in my opinion.
Stock to 750-800ppm.
You'll get the same results as 1000ppm.
As feed volume will drop,ppm's will increase and ph will lower.
Both natural phenomena...
Measure your ppm' and ph weekly and top up as required.
Also crank up the air in the feed.
You cannot have to much air ..
Once you master dwc, you'll never want to go back to soil.
Nice grow, btw...
