Too much Nitrogen? What say ye'?

[bamboofarmer]

Week 10 of flower. Dark period temps have been as low as 50F. Only 3 or 4 plants out of 24 have done this and they have all been given the same nutrient/watering schedule.

any thoughts?

What strain is that? They're beautiful. Love the colors. I'm not sure on the nutes but it looks like you have low humidity.

random seeds from mexican brickweed. I think they are pretty sickly, but i agree, the colors are beautiful.

Wow so i guess what I've read about low temps at night bringing out the purple is true?

Just a thought. Nitrogen or ph too low, combo, and 50F caused N toxicity and locked out the potassium on some latent genes. May want to keep viable. 4 of 24. ??

Not sure. Out of 24 plants in the room, only 3 or 4 look that way.

Sounds like it makes sense, lol. I think the small container might have compounded all my mistakes as well.
What do you mean by "May want to keep viable"?

A mother to clone or self for the color trait.

Can it photosynthesize like that? I think she's dying.

Reveg a few.

What medium and nutrient are you using?

 

[bamboofarmer]

Reveg a few.

Seriously? ok i'll try.
Would you chop or do you think there's more to go here? Starting week 11 tomorrow

 

[bamboofarmer]

What medium and nutrient are you using?

Recycled potting soil mixed with some local dirt and vermiculite.
A little grow big during veg, and Espoma organic bloom booster during flower. A little cal/mag plus here and there.
Haven't given any nutrients for a month, aside from the cal/mag maybe twice.

Hell yeah. Smart. This makes me want to get into growing from seed more. I love seeing all the phenos. He can't clone in flower though right? So maybe that silver spray to flip it male and get some feminized seeds.

Dark period temps have been as low as 50F.

There's your answer, that and genetics. Lots of genetics these days turn purple even without cold temps but they will turn almost black with temps below 68 °F or so..

Here is some bud that was in my flower room that hit 62 °F this winter lights off. ETHOS Cookies RBx.

Awesome! Does this affect yield or potency you think? Or just a bud appeal thing? I definitely want to try and get some color out of my purple kush.

I've noticed no difference in potency the major difference will be color, yield will definitely be reduced by cold temperatures as it's slowing the plants metabolism substantially, especially if it gets too cold in flower. Cold slows or locks the sugars up in the plant to my understanding and cold sugar doesn't flow well.

If you want to crank the colors I would let the plants just about finish within a week then crank your AC down to 62 or 65 ish °F for a few nights before harvest, should help bring out the purples.

Yeah that looks nice, man! I think mine is more the result of a bunch of mistakes and lockout, rootbound, etc.
