This is my fourth run in this facility and the fourth time I've had this issue. It starts happening right after stretch. Symptoms are a yellowing/browning of edges of leaves from lower half of the plant, working it's way up the plant. Effected leaves eventually completely wither into a crisp and fall off the plant. Plants are on an auto-feed system fed 4 times a day. Coco is always moist.
Nutes - AN Sensi Coco Bloom A/B
- AN Big Bud Coco/Overdrive (depending on week#)
- AN Bud Factor X
- Have also used Canna Coco A/B with same issue
Coco - Canna bricks expanded and flushed down to feeding levels
Strength - Between 450 and 550 ppm
Ph - Between 5.6 and 6.2
Runoff Ppm - Between 550 and 850
Runoff Ph - Hovers around 6
Temps - 68-74F
Relative Humidity - Between 55 and 65%
Co2 - Set to 700ppm
Pics linked show the bad damage at lower section of plant, beginning stages of damage at middle section of plant, and an apparently healthy canopy that will be deficient before harvest. I get that deficiencies are normal with a flush, but this issue creeps it's way into the tops before I'm usually ready for the flush. I've had issues showing up in the canopy as early as week 5 in the past.
Sorry for not color correcting the photos. Also sorry for not attaching the pics here at the site. Tried to 3 times, but each time the 'attachments' pop-up just whited out and lagged up.
