phosphorus defiency?

Am i correct to say this is a phosphorus defiency?

Skunk #1 mother first week of flower:

It's a little hard to say from the pic but it looks a bit more like Potassium def. It could be a mixture of both. Post what you're growing her in and what you're feeding her, then we'll figure out which nutrient levels are insufficient.

Growing in organic biobizz allmix soil, haven't starting feeding properly yet, but i have biozbizz grow biobizz bloom & biobizz fishshit.

whats your ph at?

cal-mag-K

flush 3 times container capacity with ph 6.5 water...mix balanced nutes with cal mag to last gallon
