Leaf discoloration help

Looking for tips on what is causing this discoloration on the tips of my leaves - any help is appreciated. Thanks!

Hellure…
Looks like calcium deficiency. Are you using cal-mag?

Thank you for responding! No I am not - do you have a brand you recommend

Hi… any liquid one will do. Just follow the directions for mixing it up with water. I also adjust the ph to 6.5 when using living soil. I think the ph is lower is using liquids. The leave that are yellow will stay yellow even after using the calmag. It will help out your buds this late in the grow.
Happy Growing!
