BCN critical mass xxl
Coco and perlite. Running a 600w hps light with ballast at 400w. About 45-55% humidity. Feeding flora triple series with calmag and feeding water ph is at around 6. Temps are between 25-30°c.
Day 17 and the leaves on one of my bcn xxl critical auto flowers are going yellow.
Flushed 2 days ago because thought maybe I nuted them to early.
I use a 250w hps light with ballast.
Any ideas?
