Is this a boron deficiency?

Or phosphorous? I'm probably two weeks away from harvest.

My grow log for this is listed in my sig. This plant is Vanessa.

looks like phosphorus to me... great job otherwise. The myco fungi are responsible for a lot of the ability to pick up P... work on developing them more strongly during early veg to avoid this in the future. For now, a good finishing supplement high in PK would't hurt.

I'm hoping to pick up some Foxfarm Cha-Ching tomorrow. I found a small hydroponics shop that supposedly carries it.

Thanks.
