Deficiency Problem Day 85 PLEASE HELP!

hey guys, i have question i need help with ASAP because i am on day 85 on my Blueberry Autos and the leaves on 2 of the 4 plants just started to turn yellow in the past day and half and i dont know why? the only thing i have changed in the past week or so would be that i am no longer feeding any nutes since i am only about a week or so from harvest. This is my very first grow and everything has went flawless up to this point and the buds are so amazing i just want to know what to do to fix or stop this issue as fast as possible. Thanks for your help guy @garrigan62 @Donaldj @Majiktoker
Here are some pics of my biggest plant that started the yellowing yesterday.

How big is your pot size?

5 gallon pots

If I may @Majiktoker and @Dumme

It’s totally normal that your leaves are yellowing since you have stop given them nutrients, it’s part of the natural process of dying of your plant that far in flowering (since it’s an auto flowering)

Hoping that’s helping you @pbs86😀

I agree with @Niala at this point its normal

Without nutrients, your hungry lady is bound to start chlorosis. A 5gal grow pot with that much top growth, I can only imagine shes probably root bound as well and simply cant find anything to eat. Chlorosis is also normal in the late stages of life.but it might be pertinent to post a close up picture of a leaf.

Edit: Ah, you guys beat me to it… :wink:

that is my tallest plant by far. she is at least a foot taller then the other 3 that were planted at the same time. Pretty sure the reason she grew up so much was because i dropped a light on her late in the veg state and broke a large limb off. Here’s the pic i am going to post for bud of the month.
Total insanity-


Woow :heart_eyes::stuck_out_tongue_winking_eye::tongue::+1::ok_hand::eyes::grinning:, it’s a beauty :grinning::+1::ok_hand: @pbs86

There is no deficency going on here.
your plant is nereing it’s end and by not feeding it as you have said. the plant is drawing from it’s self that cause’s the leaves to turn yellow.
So you don’t have ro call out the National Guard lol

You’re welcome @pbs86, it’s always a pleasure to help a fellow grower :grinning:

They’re turning yellow for 2 reasons:

  • They’ve almost finished their life cycle

  • You’re no longer feeding them nutes

Your plants are normal, enjoy…! :sunglasses::thumbsup:
