Ignore the right and left cups. Those are just some sick, twisted science experiments at this point. I dont know what they're doing, but I'm gonna let the little freaks grow til the end.
Deficiencies almost always occur from a PH malfunction. Try bringing your PH up to 5.8, I believe you said you've been doing 5.6. Not sure that would be the issue but some strains can do a little better. I also assume you are feeding these girls following the BLG feeding schedule.
I'll move my ph up a bit to 5.8. Following your BLG feeding schedule otherwise. They will need transplanted soon, so that will likely be the next time I feed them.
Try lowering the dose when feeding and feed at 5.8 the dosage your giving might be to strong. How close are the lights to the plants?
It was definitely just a tad high on the nutrients for the babies. These autos have been fairly finicky the entire grow. I've found success in lighter feeds, ensuring good runoff every 2 days. Ph 5.6 has been the sweet spot, as it climbs over the 2 day period.
Probably going to harvest in a week or two! Now I need help with THAT!
