Leaves going all spotty and unhealthy looking - week 7 flower

This issue with the small/slow bud growth and culminating into dodgy looking leaves has been going on for a few weeks now. Previous to doing a straight water flush I had been feeding daily with a soluble NPK fertilizer and additionally a K bloom booster. Also Epson salts once a week. I'm suspecting nute lockout and possibly a Calcium deficiency. I had some issues with my soil pH - it was around 5. I since have flushed it really well with around 10l of water yesterday and the pH looks ok around 6 (43cm pot soil/coco mix). I have ordered some Calcium Nitrite and was going to apply some of that with some Epson salts and a bit of bloom booster. What are your thoughts? Is it too late to hope for recovery and more dense bud growth? Thanks

I've gotten much worse by week 7, the plants are getting ready to die and give up the nutrients in the leaves to preserve the buds.

Hence the color fade. You have yellowing of the veins though, I'm not familiar with that.

Don't worry too much about it, you're getting ready to harvest.

Thanks, yeah not too much I can do now. Next time I'll keep an eye on my nute levels and pH etc. It's my first grow in pots and indoor so it's a bit of a learning experience.
