Keep getting yellow leaves in flower. Increased PK...

yellow is a normal fact in growing bud if you want you can add nitrogen it can use some (contact me for easy recipe)

Nitrogen deficiency causes yellowing from the bottom up.

Hey there OGHarry, this process is called senescence , when the plant gets beautiful "fall colors". It's not a nutrient issue like lock out or Nitrogen deficiency , you can tell from the uniform fading all over the plant . All it means is that these genetics do that and that this plant is perfectly healthy and nearing the end of its life . Hope this helps ! 🚀

@HarrysOG hi harry your plants look fine mate The older leaves will naturally yellow as you get closer to harvest because your plant is using every available bit of energy it can find including the leaves which is why their colour is fading Your info on trichomes being completely milky with 15-30% amber is the best time to Harvest I hope this answers your question
