Calcium deficiency?

This is a pic of a leaf from my blue mystic grow currently in its 10th week (indoor, soil). I was planning on starting to flush it staring next week.

The leaves stated yellowing about 5-6 days ago. Is this calcium deficiency? It’s grown in soil and I have been giving it FF nuts.

I think it's pretty normal for the lowers to start to fade out towards there end of the grow. Even if it was a problem, I don't think it's something you could correct this far into the grow.
 
I agree with Zogs. This late ya can't fix it but I wouldn't really worry about. Are you using tap water or RO water? well water can cause the same. I think her run is about done...
