Yes, excellent work Joe.

I have an issue that I am having a problem pinpointing. Ca or Mag I think but not sure. Any ideas?

Good call, not always a cal/mag def. I found this site when I google, for Cornell U.

pale green plant i general, yellowing leaf that has a "purple" blotch and slowly shrivels one finger at a time...in my opinion lack of utes i general...i see specificly n and p ad possibly zinc but hard to see for sure, but looks like either lack of nutes or ph issue

I am glad someone updated the guide to sick plants, with better and more examples. I have been here many times to diagnos things.

awesome guide joe! Ya, my pics were outdated and it was hard to update with my thread locked, mods did unlock it at my request, but adding new pictures was hard, 10K helped me pic out the ones that were good enough to post. I always tried to make a flow chart, but no matter how hard I tried there were too many variables to come up and the bigger it got the more confusing, there were just too many situations that could change depending on what you threw in the equation, but your flow chart is nice, not too big and very helpful! I am going to be updating mine soon, Im going to make a thread and ask peeps what they want to be updated and added cause I am all out of ideas, but this thread is awesome and I'm glad to see someone else putting up a sick plants thread

Hi All,

Just after reading through this thread, some plants of mine have taken a turn.
They are in soil, in week 6 of flower and being fed Green Planet Bloei A and B every other feed (whereby, you alternate between flush and feed ), as per the feed schedule.

The yellowing is mostly to older leaves, but not necessarily lower on the plant.
After reading through this very informative thread I believe it to be either Nitrogen or Mag deficiency.

What's the consensus?

good job joe.
