Is this a phosphorus deficiency?

Looks and sounds like temps getting to cold. Most likely its dropping on you when lights are off. Two things happen when temps get to low. One the plants will slow growth down, two they can turn purple.

It's odd that only one of the four plants is showing this. The other three are thriving. Daytime temps are between 73-78 and dark period temps are 62-66. I did have some difficulty with fluctuations near the end of veg tho. One thing that stands out in my numbers is that the ppm in the soil runoff is about half the amount of the other three plants. But soil runoff can be complicated. Just thought of something aswell that this is the plant closest to the two most intake holes at the bottom of the tent. Thanks for the reply.

Could be a genetic trait. Some plants will get purple leaves when in flower...

Thanks for your reply. I'm pretty sure it was a combination of temp drop at night as well as being the plant closest to the intake holes that suck in the cooler fresh air.
