those meters are inaccurate junk.

to me they appear to be nitrogen deficient. it looks as if it first showed in the oldest growth and is progressing up the middle, yet to touch the new growth. this is a classic sign of a nitrogen deficiency. treat with a readily available source of nitrogen. yes i know you are in flowering, but nitrogen is still used during flowering. i assume you are trying to stay organic?

you are in oregon? when do you think optimum harvest time would be?

im curious on how many harvest you had under your belt? i see you give tons of advice. usually if there is a n deficiency the whole plant will get pale in my experience and the big fan leave stems will not turn purple/red. new growth will also turn more pale faster than the older growth. listen to rusty
