Hey guys, thanks for taking the time to read this! Let me preface this by stating that I am very well aware my growing setup is not ideal and has made things significantly more difficult for me. I was led astray by a local hydro store in the beginning and had to scramble my way back. I think I've learned much faster because of it, though. This is my first ever grow. Onto the important stuff:
As the title says, my DWC plant is showing nute burn at incredibly low ppm levels. Everything was fine and she was thriving at 450ppm until I gave her her first major defoliation during week 2 of flower. I knew this would stress her and I'd have to cut back, but I havent been able to stabilize since. My setup is as follows:
Strain: [Purple?] Runtz (bag seed from reputable source)
2x2x3 grow tent
1x 3.5 Gal bucket
HLG 135w (3000K)
2 outlet air pump with 2 stones
Plagron Nutrients
Ac Infinity T4
Monitoring both air and reservoir temps, as well as checking pH and ppm multiple times daily.
Res temps: 63 - 69 degF
pH: 5.8-6.3
RH: 55%
Tap water: 44ppm
As previously stated, things were hunky-dory until the first couple weeks of flower, when I did a hardcore defoliation (i.e. all fan leaves except the top 2 nodes). I cut back the nutrients to 200ppm (from 450ppm). I made the mistake of also turning my light up *slightly* (it is at minimum Voltage and Current at all times and is still almost too powerful for a 3 foot tent). Changing 2 variables is never good, I know; very unscientific and I should know better.
When I noticed 2 days later that nute burn was setting in, I turned the light back down but that didnt save anything; the nute burn continued. I have been slowly decreasing ppm levels constantly, and have gotten to where I am now (80ppm) Around this time I noticed my pH meter had decalibrated by ~1.0 pH, so shes been sitting in acidic res water (seriously, how did I overlook this?) I have since gotten a much better pH meter (about 2 weeks ago) and calibrate it regularly, and I was hoping this would solve the issue.
1 week previous to this (3 weeks ago), I also made the mistake of going BACK to 12 dark from 13 dark to try and slow maturation (my cousin said it should be okay and he has been my guru through this, and he had not yet been mistaken), and think I sent her back into veg for a couple days. Branches started growing again and bud growth halted altogether. I went back to 13 and saw minor bud growth again, and am still at 13. Because of this, my pistils seem to be maturing disproportionately (i.e. the ones before reveg are all orange and quite old, but still seeing tons of new ones) This grow was going so perfect, but I just had to fuck it up.
She's currently sitting at 85ppm with ppms rising (~20/day) and pH dropping. On the rare occasion, the ppm will drop slightly during the day (like margin-of-error levels of change), but I can't for the life of me find a correlation, I do everything the same. At this point adding ph up/down increases ppm more than I would like, so I don't even have margin to add nutrients. I follow Plagron schedules for nutrient proportions, but not volumes; I feed to a given ppm. I have changed nothing outside of ppm and pH for the last 3 weeks.
I'm not sure what to do, and any guidance would be appreciated it. I have literally read every tangentially related thread that google has presented me and I cant find a solution. At this point I'm just about to flush her and leave her until she gets chopped, I'm all out of ideas. What do you guys think? Pictures attached ( first two are pre- and post-defoliation, then 5 more pictures all taken a few minutes ago.)
Thanks again, everyone!
