Supposed to be a 55 day strain.

Pics below. It happened over the course of under a week. A few leaves started turning yellow and now about a third are yellow and i found one leaf like this.

Using dyna-gro bloom every other watering. coco/perlite/composted manure/worm castings mix.

I don't have a ppm meter, but I pH'd my water to 6.2 and it came out 6.6
