Hello,
Im having problem with 1 female auto i have ... The problem started when it got to flower. The leaves started having this spots, 1st i was thinking ca/mg def but it wasnt. Then i was thinking ph lock but the runoff is 6.3-6.5 on water going 6.7-6.9 so i dont think its ph problems.
The leaves are next level dry... i water around 750-1l every 3-4 days ...
If anyone have anything to say i would love it.
Thank you

I dont do run off, but to me 6.7 in with 6.3 out says the PH is low and causing a lockout. How much longer do they have? What is the temp? Is this a purple strain?

They are in week 4 of flower ... i guess they have around 4-5 weeks more ... and yes its Devil Cream Auto from sweetseeds its purple strain

I agree with Rwise about the lockout, looks like for awhile too, but I can't see your pictures very well, old eyes,lol
Can't tell if you got them tied down or not, but if they are I would release the bondage.
I've grown several DarkDevils from SweetSeeds before and I never got over 3ozs from any of them either, they were always much smaller plants than all the other SweetSeeds cultivars like CrystalCandy, RedPoison got huge but it was not an autoflower either,like they said, GreenPoison always grew to nice large autos to, as did all the other SweetSeeds plants I've grown,
I can't say that about the DarkDevils though, they stayed small, might have been I fault. I don't know, but I don't think so.
Anyway good luck.
PS, are you sure your ph meter is working right?
I don't mess with run-off either, how do you check your runoff?
Are you in soil or coco?

Looks like soil. Don't give her nutrients for a a week and see how it goes. I don't have much experience with autos but when my photos are stress I just flush them with water and most of the time they bounce back. Good luck.

Yeah i use soil and its 1st run i do with this soil ... I will flush it today. And i check my runoff with ph meter i will check next time with my secound 1 + drop test to see if the ph meter is not calibrated but i think it should be ...
