It's kinda hard to tell from the pics, but it looks as though it is only some of the lower leaves yellowing, and doesn't look like a deficiency or burn to me... As a plant flowers, it starts to fade from the bottom up and is especially noticeable with autos from my experience. The plant is consuming its nutrients that it had stored during veg in the leaves, and they will continue to yellow and fall off as the buds get bigger and the plant nears the end of it's cycle...

they are only about a week or less into flower ..still 5 or 6 weeks to go...and this happened quickly within the last 2 or 3 days...it has to be a def. of some kind leaves arent supposed to fall off that early if im not mistaken...but idk....thanks for the feedback...

have you checked your soil ph?

whats your watering ph?

 

[DubV]

What's your runoff ph bro?

 

[droskee420]

have you checked your soil ph?

whats your watering ph?

Yea the soil ph is 6.3 -6.4...and watering is 5.9- 6.0

 

[droskee420]

What's your runoff ph bro?

runoff is 6.6-6.7

 

[JM]

ahhhh that may be adding up to your issue... watering ph should be same as soil 6.3 - 6.4 if yu been watering like that all along... you'rew carrying it down over time



often when you compare plant issues that are a result of ph and the chart... it becomes clear why an issue is showing up.

ton of other good links here: https://www.autoflower.org/f7/announcements.html

 

[JM]

hmmm... so runoff is 6.6 6.7?

how did you measure soil ph?

if runoff at 6.6 - 6.7 then waterin 5.9 - 6.0 should be good.

puzzling

...gets quarter strength nutes havnt raised the nutes dosage since shes been getting fed and no problems till now.

oh... well judging by the potassium def I see... maybe you are jst ready to go full nutes...

see in the tips of the leaves? thats the beginnings of potassium... but I wanted to make sure it wasnt ph related so we wouldnt steer you further down the wrong path.

Yea I don't understand how your runoff is that high with what's going in is that low?
