Hi. I’m new here and new to growing. Here’s my issue; I’m growing White Widow in 10 gal grow bags using Fox Farm nutes (Big Bloom, Grow Big and Tiger Bloom). I’ve been using them at 1/4 strength. Just stopped the Grow Big at week 3 of flower and now just using Big Bloom and Tiger Bloom. My leaves have started to turn yellow. The soil pH is between 6 and 7. If it is a nutrient problem, wouldn’t the pH be off? When watering or feeding, I give them a quarter gallon. Is that enough? Any help would be greatly appreciated. Thank you in advance.

Have you got a pic of the plant.
Really helps a lot when we can see the issue.
The arrow is where you put up your pics.
Wait till they fully load before sending.
And welcome to the neighbourhood.

Should take a couple days to dry back.
Lift it again after watering to get an idea of how heavy it is so you’ll know when to water again
And keep a drench to drought cycle going. They like it better that way. 
You can also pluck those yellow ones too.
They won’t green back up. And can bring mold.

Awesome. Got it. Will increase nutes to half and add grow big back in.

And hungry, had the same look awhile ago until I started nutes and lots of water outside takes more than inside

Welcome to the forum.
Plant looks pretty good.
I use the ff nutes and always feed full strength. Water only between feeds.
This might help if you dont have one.

Hello there.
Your plants are in the same phase as my OG Kush (early flower with some yellowing leaves). I water appropriately but the yellowing leaves appear in all four of my plants, and then falloff or I remove them. I can see that the yellowing leaves are superfluous to the developing colas and flowers, so I believe (as some have suggested) that the plants are pushing necessary nutrients to the flowers and leaving the superfluous leaves to whither away. If the rest of your plants are healthy and your flowering continues, you are good to go. I grow outside in central VA in a small 4x6x8 greenhouse and only water as needed, remove mildew and bugs, and provide a bit of nutrients. I’m doing nothing special for my yellowing leaves, since I view them as part of the growing process. My plants are healthy and the remaining colas continue to receive adequate water and nutrients to provide a good harvest.
Last year, my four MasterKush plants went through some similar yellowing and had bud rot into the final flowering phase, but produced 16 to 20 oz of harvested buds which I enjoy daily to relax, relieve my arthritis, and fall into a gentle euphoric sleep. Thank you ILGM!
Captain, you should enjoy a good harvest as long as you keep an eye on the bugs and watering.
Blessings
