Hi everyone,
First time posting, so thank you in advance. I am on my second DWC grow and can’t figure out why the ppm of my nutrient solution is rising. Below is a summary of conditions:
- 2nd week of flower (after estimated 2 weeks of pre flower, 4 weeks after lights were flipped to 12/12)
- My last water change was on 4/13/22 PPM leveled off at 1100 and then began rising to 1230 over the next 5 days.
-Ph settled at 5.8 was relatively stable during this period and no additional ph down or up was added.
- water level also does not change. I have a float valve in the res connected to secondary resovior of plain RO water which is released as the nutrient solution is consumed or evaporates.
As such, one would assume that ppm would drop as the nutrient solution is diluted with RO.
- Ph and ppm are constantly monitored blue lab meter. Solution was rising by 30 ppm per day.
Additionally during this period pistols on some colas began to turn amber (seemed early) and I noticed several fan leaves throughout the plant turning yellow. Location of the dying leaves was not consistent, was more or less throughout the plant. Some tip burn was also noticeable.
I feared my nute solution was too strong and recently dropped the ppm closer to 900 and am not seeing it rise anymore, but am still puzzled by what was causing the ppm to rise given the circumstances. Has anyone else experienced or can explain this phenomenon? What am i missing?
Finally can anyone help me confirm
If this was nute burn or some deficiency driving the discoloration and the early darkening of the pistols. A few photos of what in am seeing attached (lights are off for the night, but I’ll try to post some better images of the discolored fan leaves tomorrow)
