Hello,
I am having a bit of a problem figuring out what is going on with my grow, thought I would log a formal plea for help.
The plants are Purple Pine-berry feminized.
They shed the seed on 23NOV
Grown DWC with approximately 5 gallons of solution
Grown under P450 LED - 24/0
Nutrients: Advanced Nutrients Grow-Micro-Bloom plus voodoo juice, B-52 and Hygrozyme
Environment:
Air temp: 75F
Humidity: ~40%
Reservoir solution: 64.5F
Current pH range: 5.4-5.9 drift over a couple days (more like 18 hours) and then adjust back to 5.4.
EC: ~1.2 or 600ppm (0.5 conversion)
Tap water is about 0.2 out of the spigot.
History of the issue:
Plant of the left (A) showed signs a week before the plant on the right (B). As only one plant showed signs of the issue, I assumed it was plant height in the net pot affecting oxygenation/over-/under-watering of plant A, as all other variables would have been the same (same solution and growing environment). I lowered the solution level and the leaves drooped further - plant B remained unaffected.
I raised the solution level back to even with the netpot and the situation more or less remained consistent. at the time the EC was about 0.8 (400ppm) as the plants were only just developing their second leaf set.
I did a reservoir change as I was heading out for a week long trip, the pH and volume were the same, but the EC was a little higher, more like 1.0-1.1 (500-550 ppm) and left for the trip.
I know my parameters are not too conducive to root rot, but I was concerned... snapped a picture and they look plenty healthy.
The plants seems like have ready access to water, ruling out the under watering in my mind. Also as the solution level is about .75- 1 inch below the net pot I think over-watering can now be ruled out.
So what am I looking at? Is this nitrogen toxicity? I am feeding basically what pans out to 1/4 dosing of Advanced Nutrients, which is both recommended by AN and the general starting point for young plants I would say (please correct me if I am wrong)
A:
Just noticed (now that the LED is off for pictures, plant B could possibly have some burn on the first leave set, what do you think??
B:
Ill turn it over to the experts here. I greatly appreciate the help!
