So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore?

Thanks for answering!

To me it's mean you are under feeding , I mean I can see magnesium def , N def , traces elements def, I would feed more before the flush. Concerning the leaves , the plant did not let them fall down so she needs them , she is sucking the last nutrients out of it ( sign that your feeding is on the low because she's near the end but not that lose to start that senescence aka late flowering yellowing ). Unless 70% of a leaf is damage the plant will use it

Hi, you are right, your plant cannibalised herself for the stretch into flower. So its an automatic, and her life is terminated. i wont e confused of the yellowing now, you cant do big things or wonders. concentrate to the flower.....As you havent filled out the data schedule for the feeding i cant get to detailed.. Stay with your blooming fertilisers. give her some molasses, that feed the microbacteria in your soil( and helbs the plant to absorb nutes). She dont look to bad, its better to have a defiency than an excess. Keep the magnesium and give her molasses and blooming fertiliser... for 10-12 days more... after that she will be ready to flush and harvest ... greetings

This looks like a typical nitrogen deficiency to me as the nitrogen in the older leaves is transported to the newer ones.

What nutrients do you use and how much ?
