Is this phosphorus deficiency?

[grou]

I had cold temp problems, which i resolved 3 days ago. My guess is it caused phosphorus deficiency in plants.
Also, my temps during lights on is 24-25 celsius and 19-23 should i lower night time temps? Any ideas how?
Temps outside the tent is constantly 8-9 celsius

They look ready to harvest, you are 70 days in on 12/12, how do the trichs look close up?

Trichs are not ready yet only 30-35 percent milky and 5 amber

They look a nutrient burnt to me, have you tested the run off.

AFAIK plants don't/can't have a deficiency after 3 days, the leafs are food stores.

Good point, could also be nutrient lockout from salt build up, it looks the same, I would flush with a very weak nutrient mix.

I actually thought it was build up and flushed them with water on 28-29 january but
Most of people here tell me its deficiency.
I fed them ripen 4ml/liter twice before water flush
