First grow

grow lights + photography make things look paler than they are... so if you ever remove a leaf, go look at it under normal lighting and i bet it is fairly lush.. or more lush than you expect. if still pale in normal light, probably needed a bit more nitrogen. the hippy-dippy science behind a lot of marijuana brands is supremely suspect. amounts more to marketing nonsense than anything real.. another ply to separate you from your hard earned money. so, if 'their' instructed dose cut out too much N in bloom, that's probably why it happened. giving half dose isn't the best idea either for a large, growing plant. that's something you do for a young plant, unless the instuctions are also bogus, which does happen -- see Fox Farm Trio, lol... instruct you to waste half your fertilizers so you buy more sooner, bwahah. i see absolutely no signs of K or P deficiency. you can use a leaf chart to see this and make your own assessment.

under fed.

She is in week 14. There are no amber trichomes yet

In welcher Woche befindet sich die Pflanze? Die Blätter werden zum Ende hin Gelb, das ist nicht weiter schlimm.

If your near the end the leaves do start to go. If you still have a few weeks left, then there wasn't quite enough nitrogen provided while flowering.
