Thanks for steppin in 420 Gaurdian
Does he have any earthworm castings? It's a first-line response to all problems in the living soil realm. I seem to recall that Mr A tends to run his a little yellow anyway, doesn't he guys? Is this a Dark Devil Auto? The bigger leaves are simply turning their colors, at just the right time, but you do have what appears to be too much yellow.
Does he have any Langbeinite?
When I saw the picture my hand instinctively reached for my box. I scratch it into the surface and water in. I never measure, just feel my way into it.
He won't hurt you if something happens to the plants. At the stage they are right now he'll get a good harvest no matter what. You could lose every leaf on the plant and it would still finish. Maybe not as full, but it would be worth the grow. Take a breath and enjoy the plant. She is a pretty thing.
Yellow leaves per se aren't a sign of plant health. I've got plants and they all have yellow leaves!!
Look at the calyx - where the white hairs are coming out - that's the business end of the plant.
In your pics that part of the plant is still healthy and growing and looking GREAT.
The only thing I've ever given a yellowing plant this late in flower to keep it going is:
worm casting tea - worm castings (1/2 cup) with some alfalfa meal 1/2 cup and some kelp meal (1/2 cup)
Kinda late tho for that... it's not going to change the color of the leaves.
I don't know the strain your growing there but some strains do yellow quite a bit at this stage. If I was you and I'm not. I'd be in a panic.
Fear not young grasshopper... relax, do not over react.
If anything over watering.. let the pot lighten up before doing anything other that brewing up some compost tea. Adding chemicals to a soil grow is going to make matters worse. You will be fine. sit back and enjoy the fall colors.
Here's a pic of mine - mind you I do not trim/cut/pluck or otherwise disturb my ladies once they are in flower. I let them go .. yellow is early fall color... next they may turn orange or just fall off...this plant is completely fine and actually excelling at flower production.
Those big leaves have collected lots and lots of energy from the lights and stored it in the leaves just for this time in its life cycle. The plants flowers are asking the leaves to give up the nitrogen/ chloroplast / leaf protein.
If you look closely the yellowing is mainly those larger older leaves.. there's still green going on under those yellowing leaves.
My suggestion is to sit tight - don't over water, take a deep deep puff or 3 and relax. All is well.
Bob, your yellowing is indicative of finish, but OP's yellowing is far(!) too widespread and over the top and indicates lockout.
That said, there's nothing he can do at this point. Adding any amendments this late in flower won't reverse the issues, it'll just ruin what's left of those flowers. At this point his terpene profile is gonna' take it right in the old pooper. Best thing he can do is flush DTW (drain to waste) with ph-correct water for a week or so, then cut 'em.
I can't suss out what caused the lockout, but it seems like the effects were very sudden onset, too bad it happened while plant-sitting but it looks like the caretaker wasn't at fault.
Btw, Bob, pretty plant you got there-details? [emoji846]

I agree with DoctorGonzo. Yellowing from the top down with crispy leaves looks like nute lock-out. As a healthy plant naturally eats it's leaves late in flower it will present from the bottom up. I'm not sure of Mr. A's soil make-up and previous nutrients given to the plant are, but I would flush with straight water and keep an eye on them. Water corrected to anywhere between 6.2 to 6.8 pH should work for flushing this late in the game.
Good luck Guardian. It is a noble deed you do for a friend in time of need.
Thanks for your advice, I'm not going to flush it as it's a living soil and I believe that to be a bad thing, I could be wrong tho. All I need to do is get them a few more weeks and I think bo has the right idea, sit back and enjoy.
I would take some of the EWC that you bought and put a cup in a bucket of water and let it sit and stir it up... let sit over night or until the next watering and water in.
Stick your finger in the soil down to your 2nd knuckle - is the soil wet? If so don't water. Lets get dirty ... and take a pic of your finger ... ok.... creepy. Still funny, gotta laugh at that right?
