Phosphorus deficiency?

Do you feed it any nutes or teas, or only water? What is the pre-fert ppm of your tap water? Have you checked the pH of your runoff? Did you mix any dolomite lime into your soil?

No point letting water sit to evaporate chlorine. Most municipalities treat their water with chloramine, which does not evaporate. Besides, chlorine is one of the micro-nutrients that plants need.

What is Up Country? I can't find anything about that anywhere. Anyway, the soil looks really black and dense. Doesn't look like a whole lot of perlite. How do you judge when to water? Lift the pot.... X number of days?

UpCountry is a commercial line from Fox Farm. It's not as juiced up as their regular line. I mostly lift the pot and stick a finger in her.

Seeing as your other two plants are doing fine, it may just be that the genetics of that plant don't jive with your setup, assuming you are feeding them all the same thing. Maybe the genetics make it more susceptible to root rot or something else. Is it Blue Dream the cut or Blue Dream from seed? Maybe just don't run that cut/strain again?

If UpCountry is a commercial mix, it's probably not amended with much. What all did you mix with it?

Hello everybody, i am experiencing something that i think might be a phosphorus deficiency but i am not 100% sure. it started on the bottom 2 fan leaves and is slowly spreading up. Im not sure if i should flush the plant then add nutes or if i should just add some extra phosphorus in the next watering. and if i do flush then how long after do i add the nutes? i havent been adding nutes due to the nutrient rich soil so im confused how i got a phosphorus def. ph is adjusted before watering to 6-6.5 and i am not overwatering and temp is good along with humidity. i Have not been checking the ph of the soil and i dont think FFOF is ph balanced. could this be a nutrient lockout due to the rich soil or is it a deficiency? and any ideas how i could get a phosphorus def in nutrient rich soil? any advice helps, thanks guys! Dont mean to hijack just saw nobody has posted in a while.

Strain is double bubba
3 weeks into veg (started from clone)
medium is Fox Farms Ocean Forest Soil
Temp-75
Humidity 35%-40%
using CFLS for light
ph- 6-6.5
No nutes added
Watering every 2-3 days

2 different plants here, indoor leds with normal 'rested' tap water, in ocean forest smart pots. At about 100 some days from seed. Does this look like P deficiency or something worse?
@fdd2blk should i be chopping them down soon?
Thanks everyone

I'd have to see some closer pics.
