Need help turning purple strain purple

[hakop]

Hey Farmers
Just need advice on what I’m doing wrong

Growing a purple strain
Clones are all in house
Nothing out sourced

Nutes I use through out the grow are
House and Garden coco a+b
H&g Nitrogen boost (in veg only)
Calmag botanicare
Liquid Karma botanicare
Big Bud by an
Shooting powder
Athena Fade last 2.5 weeks then straight water

I can’t get them to purple
Friend said give Athena another try
(Use to run Athena before I got this cut)

Tried Athena while adding same additives
Except for shooting powder and I gave Moab instead
And boom purple is there quality and yield weren’t tho
So I made the switch back did everything exactly the same and they stayed green

Just wanna add when I had the runtz cut
It would turn purple with the house and garden mix using shooting powder without Athena fade

I’m just lost can’t figure this out

Growing in 3 gal 100% coco
Under Gavita 1700 leds

Thanks!

I do
I’ve lowered the ppfd
Room gets to 63 at night
I don’t know if it’s a good idea to push it more then that

Ok well I see you have some white stuff plant on left front make sure it’s not mealy bug. Plants look good I would big leaf them. The last three weeks water with just pH 6.4 the purple will come at the end.

Did you ever find out what was causing your plants not to fade properly? I’m experiencing the same issue with Athena.

My white widow started turning purple on the leaves and buds once the temperature dropped down to around 50 fahrenheit (10°C) at night.
Looks good with the late-flower yellowing of the leaves.

nope still doing trials lol
Switched back to Athena and now it’s barely purpling up
If it does purple up this run the way i want it too I’m just gonna try a different cut from someone else
