    Default Phosphorous Deficiency ??

    Hi

    I am a few weeks away from harvest, this is my first grow.

    I have a healthy girl that has a few leaves showing what I think is Phosphorous deficiency. The rest of the plant and buds look great to me.
    Up until now I have had no problems. I am using a tomato nutrient with medium P. I am feeding this at 50% of the dose every other watering (I water about 3 times a week)
    I am growing in Westlands General Purpose with added John Innes compost


    I keep my PH about 6.6 - 6.7

    I grow in a greenhouse and bring plants in to my house every night.

    1. Is this phosphorous deficiancy?
    2. Should i up my Nutes to 100% every other watering or perhaps use 50% every watering.
    3. Anything else ?

    Thanks in advance
