Too damn hard to say by not having regular light pictures!
Take pics with the HPS OFF...
Have drain holes in those buckets?
Why pickle buckets? Use #7 nursery pots and have the same volume.....A pot that large, best be growing large plants - Overkill, if your not planing on 7ft plants.
Anyway, pH, over watering, feeding amounts (of)......Could be a few things and can't really see shit - color matters.
Hey Dr. Who, hope all is well. As I took the pictures I knew I was fucked up for not taking them in regular light, I apologize for that. As for the buckets, they're 5 gallon buckets from the hardware store. I just use them because they were easy to get, cheap and figured I wouldn't have to worry about root lock with them. I'm in a 6.5ft tall tent that is 4x4, so I don't plan on having 7 footers haha, as much as I would love to. I ran these plants on 12/12 from seedling though, that's why they're a little shorter though. How much smaller of a bucket or pot do you think I could, or should, use?
Back to the problems at hand though, I went out and bought a BlueLab PH tester yesterday. My water is at 8.6, so I got the PH Up and PH Down to correct it. However, what do I do when I correct the water? Should I water more often with corrected PH levels? Flush with proper PH or should I just water every few days as I normally do?
Thanks for your time everyone!
