If it's an Auto it's time is running out. They only grow for so long no matter what you do. That's why cloning them is a waste of time.
Don't wanna burst anybody's bubble but I wouldn't get to excited about it getting much bigger and giving you a harvest.
As for the DWC. Just keep your pH between 5.5 and 5.8 and you will be fine. Make sure you keep your solution temp 75 and below. Warm water is not good in a DWC. I use to have to use frozen water bottles to keep my temps down because I didn't have a chiller
@CrashMagnet hey fellow tote grower . I read through the thread and see a couple problems. No worries, get em corrected and I'm sure your future grows will be successful!
First, I see something about the solution being 2500ppm?! That is insanely high for any part of the grow! What's your starting oom before adding any nutrients to your water? At that point in the grow my nutrient solution is about 600ppm. Follow your feedchart. Speaking of, what nutrient line are you using? I use the 6 part general hydroponics flora line with the addition of hydroguard
Second, get that hole where your air lines are running covered up. You want 0, zip, zilch light getting in to your reservoir. Algae will cause pH swings and weird issues.
Third, shoot for a reservoir temperature in the range of 62-68f. Use the chiller if you need. Putting your air pump in a fridge will help, but I'm not sure if it will get you to that range. Experiment if ya feel like it, but keep it in that range to prevent root rot -- which will also cause pH swing and other issues.
Feel free to read through my past grow journals in the grow journal section of the forums. I've been growing in dwc/aero for a while now with great success. I absolutely love how easy it is to manipulate and know what is going on with your plants.
Also, reach out with questions. I'd be happy to help!
One last thing -- will you please put in a vote for March Bud Picture of the Month if you haven't done so already? The contest ends in a few days and I'm trying to rally up a few more votes. A link to the contest voting thread:
