I have 4 plants under grow, and a couple of them are exhibiting curious runoff numbers. I missed getting my nute-mixed PPM prior to this post, my bad. My nutes are AN Sensi Coco Grow A&B and B-52. I water/feed 2x daily. Medium is Batch64's Fortified Micro Blend coco.
#1 Girl Scout Cookies Auto, 37 days after seed, 3-gal smartpot
#2 White Widow Auto, 37 days after seed, 3-gal smartpot
#3 JillyBean Photo, 31 days after seed, 2-gal RainScience pot (transplanted to these pots about 10 days ago)
#4 Jack Herer Auto, 26 days after seed, 2-gal RainScience pot (transplanted to these pots about 10 days ago)
(I specify "after seed" since I don't know when anybody starts counting)
Anyway, I did a flush on all of them 2 days ago to get a "fresh start". All runoff were within 50 points of the flushing water (~400ppm, city tap water, pH'd to 5.7, final runoff pH was 6.1-6.2 for all)
Since flushing, I'm now down to about 1/2 of what AN recommends, more closely following TaNg's "Easy updated schedule". The 2 newer plants in the 2-gal RainScience pot are getting higher PPM runoff than the 2 more established, larger pots. Maybe this is contributing to the difference. We'll see. Because of this difference, I have increased my watering/feeding, about 5 liters across all 4 plants
Anyway, I get the following runoff numbers
#1 477 ppm, 6.3pH
#2 460 ppm, 6.4pH
#3 617 ppm, 6.2pH
#4 576 ppm, 6.3pH
I'm rather curious what leads to #3 & #4 runoff PPM being so much higher than #1 & #2. Could it be the replanting with fresh (washed and buffered) coco? Smaller containers? Different ages?
any thoughts most appreciated!
