I think this is a potassium issue. Iv amended the soil and also added kelp and a teaspoon of alfalfa meal. Wondering what you all may think.
Few other leaves look like this, pictured here.

If your talking about the yellow tips,that's generally the first sign your soils nutrients are a little to high and its starting to burn the plant. I'd check the ec/ppm on your runoff to get a good idea how strong your soil is.

So our upper leaves have been developing some burn along their edges but are now yellowing too. I've increased the gap from light-plant to 75cm but is there more to it? Unlikely a deficiency as she's fed 1/4-1/2 recom. nutes every water. Root ph is ok so maybe nute lockout? Chur.Week 11

Odd leaf bitten?Hi All,
Noticed the odd leaf like this that looks like something has taken a bite of it.
It is only the odd leaf. I had some fungus gnats a few weeks ago which are now gone.
Is there something else doing this and do I need to act?
Thanks

Since then the OGK and TT have also gotten brown leaves, the Gelato is unbothered
Could this be nutes? part of the flush process?
I have also read it could be old age? a natural thing? halp

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This is my second attempt at cocus
I work with Plagron nutrient solutions(Coco Nutrient)
I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!
