I want to say that when i started week 7 of flower the leaves started yellowing from the inside out. Now week 8 begins and a lot of leaves have turned... Any ideas what caused this?

The flowers are beautiful and i don't want to mess it up during the last week

I just pumped out 3/4 of the res and topped with plain water to dilute, hopefully it stops the yellowing. I was going to flush at 56 days, harvest between 60-63 days...

this looks like poor watering habits leading to too much dryback causing damage to plants due to nutrient burn, ph issues and possible lockout.

I am confused though as you mention your res but i see soil or coco, what type of watering setup are you using? what medium?

I would probably water with 50% the nutes I was using and try to ride it out and not let them have any extreme dry backs

What reservoir? You're in containers right? You don't circulate that runoff back to the reservoir?

Need way more info to able to help. What are we looking at? What kind of system? What reservoir and what do you fill it with and how often do you do reservoir changes?

Using coco, ebb & flow. Not a watering issue for sure, i also just realized my pH pen was off calibration, so would a really low pH cause this? It was saying 8.0 so i would pH down to 6.0... then realized after calibration it was 6.5 after mixing nutes instead of the 8.0 it showed the past couple weeks...

I think that was it... FML.

so if I follow then you were watering as 4.5-ish ph? I can only imagine that will lock things up and cause issues. I would be curious as @rkymtnman asked, what ec are you feeding at?
