Week 9, copper deficiency? Worth worryimg about at this stage?

[BigBudz2020]

hey guys just asking for some opinions and advice. Does the attached pic look like a copper deficiency? It's on the top growth on the leaves coming off the colas. She's 9 weeks old today I think she's got about another 3 weeks to go. Is it even worth trying to solveat this stage as I'll most likely have to flush her

Don't sweat it. You will get to harvest. You may not even see much change with it even if you try to fix it. Not saying don't try to fix it just don't panic.
Always good to get an idea of what the issue is, for your own peace of mind.
Good luck

Yeah thats basically how I'm looking at it. Would just be nice to know for future reference as I'm still learning. I think it may actually be a zinc deficiency.. I may never find out lol

It may be easier to identify based on how it progresses. Thread below has a link to a journal article that discusses overall progression of each deficiency:

It's for hemp cannabis, but should still be useful for medical cannabis.

It looks like lock out from high ph. I would test run off and probably need to water with a little excess run off until run off is acceptable ph/ec
