How many weeks flowering is she?

Many strains start yellowing old leaves around 5 weeks or so depending how long their flowering period is. Low N or Mg would be affecting a lot more leaves and low P or K don't present that way.

I think she's looking good and you're going to see a lot more yellowing before she's done and have big tasty colas at the end. Mild levels of nutes if any depending on what all's in the pots. Very low N compared to the P and K. If she needs N she'll steal it from the older leaves but too much inhibits flowering in the later stages.

:peace:

wot the old guy said :) looks like mine when i start flushing, could be strain trait (ie may need more N, but id change the nute solution or folier feed some lower shade leaves and see if it helps first. nute imbalances can cause all manor of nute deficiancie symptoms, NPK deficiancies start on the larger outer leaves, where micro nutrient problems start from the center of the plant and work outwards.

Look pretty decent from what I can tell from the pictures. Maybe a little N increase is in store. How do you determine when you water?

Usually I pick up the pot and feel how heavy it is

Good method and the one I do also, I think it is th best for me to use since I can much easily tell the difference between the full container versus a container that needs water. Your plants look better than alright, my suggestion would be small increase nitrogen and monitor it for a few days. See if the yellow continues to spread. Don't know a whole lot about animal cookie strain but maybe it is a strain that yellows halfwayish through flower??

It's my first grow with this strain so I don't know much about it either but my buds are sooo fat!! They're short and bushy with at least 10 tops each. I increased All N, P and K and they are a little better, but still yellowing here's a pic. This is not one of the ones that's yellowing.
