Really strong smelly buds, but yellow leaves

Grow Support Autoflowers

First plant is Wedding Cheesecake, second is Blue Dream, both day 58. Buds are beautiful, and getting stronger. But why all the yellow leaves?

Soil is FFOF. Food is GH Maxibloom and 1/4 tsp of Beastie Bloomz, 3mg Calmag, pH 6.4. light is 1000w HPS.

My only thought is the plants are entering the end of flower, and drawing all the nutrients from the leaves, and into the buds.
I’ve been growing photos for years, and this is more or less what happens in the final stages of photos. But I’m new to autos, so I’m just guessing right now.

I don’t believe maxibloom has enough nitrogen for a complete start to finish. Did you ever use a nitrogen fertilizer in veg?

Hi!
It might be the ph when the plant is in flowering the PH needs to be around 6.5 -7.0
Try giving it more alkaline water a tip for that is when u mix ur water with nutes put half a tea spoon or a whole teaspoon with baking soda and mix it well and then check the ppm or EC.
The nutes makes the water too acid and this water sits in the soil for along time, give it a rinse with 3 liters and then put the alkaline water a tip is also giving it just water with good ph and ec for a week.
This is my insight from my experience with yellowing might be wrong but incase do it cuz this doesn’t hurt the plant and also works as prevention when you are lost with troubleshooting.

Exactly. :+1: I think your good it’s completely normal at this stage. It ain’t broke so don’t try to fix it. Looking stellar by the way. :v::call_me_hand:

First of all, congrats on a beautiful run. Awesome job. In a perfect world, i think your runoff should be closer to 6.8 pH in the final weeks as @Bseis has also stated. Like @Dman1969 stated its not too broke, obviously, so this close to the end no need in trying to fix it. Youre correct in observing that she is putting everything she has into her buds by drawing nutrition from whats left in her leaves. If your pH was closer to 6.8 this would be less evident but still noticeable nonetheless i believe. Again, great job man. Awesome run!!!

Pretty common with a lot of plants. I would not stress over it as there is really nothing you can do to help leaves. They will not recover no matter what you do. Just ride it out.
