Hi all,
This box is outdoors in central Ca. Not sure why it's having problems but I am leaning towards too much N and/or too little Phosporus.
The leaves are small and stunted with a pale or sometimes almost metallic looking green/blue color.
In regular top soil, nothing fancy. feeding with water soluble 10-30-20 Peter's/Jack's Classic nutes, every time, at about 1000 ppm and 6.1 PH. I also add a little 0-0-50 because last year I had potassium def. in mid/late flower. So, is this Phos. def? and/or too much N? Or something totally different?
As you can see in the picture, all of its neighbours are quite happy in comparison.
Thanks in advance!!!

Too little Phosphorus. P deficiency presents as those crispy dead leaf blades. Sometimes they are brown, sometimes they are greenish but they're always crispy.
