Here are pics of two leaved that show problems. Both were taken from top colas within a foot of the light. At first I thought maybe it was normal at 6 weeks of flower, but only the top fan l eaves under the brightest areas are looking like this. Lower fan leaves are green.

Growing in coco/perlite with high frequency fertigation of 7x daily. Input EC about 1000, runoff is higher and I've been working to lower it. I may have diluted my nutes too much getting EC down.
