Red Pistachio-2nd time around

Week #9-Sep 24 to Sep 30 8/25-Plant continues to do nicely. However, I noticed a couple of the top fan leaves have got some small yellow/gold spots developing. I've been using the same Bloom feed for this plant as my 3 Bears Smile which is 8 days further along. I'm wondering if that might be causing the problem. 8/27-After getting some great input from some fellow growers he on GD to a question it turns out that my Ph/EC instrument had lost its calibration and was underreporting my EC levels 20%. Now I've not got my instrument properly calibrated, I adjusted my inputs to the proper levels, did a mini-flush w RO Ph balanced water, and then watered with the correct mix. Will monitor progress from here and hope that is sorted out for the final 2-3 weeks of bloom. Another lesson learned. 8/28-Watered to runoff and the inputs and output are spot on. The yellow spots I was getting seems to be under control now. Now new spotted leaves. Did some minor leaf removal to get more light into the middle of the plant. Bud sites are starting to bulk up. 8/30-Good week. Plant is shaping up nicely. I think we have another 2-3 weeks left.
