Me pasa lo mismo creo que es deficencia de potasio por mucho nitrógeno o por no haberla alimentado

Try feeding some calmag, looks like could be calcium deficiency and possibly phosphorous deficiency. The ends getting burnt could be nutrient burn, that isn’t too much to worry about at this stage

Also are you feeding/ watering until you get some runoff to avoid nutrient buildup

Looks to me like it's nutrient related. Most likely too much. What's your grow medium, how often are you feeding and how much. What pH are you adjusting your water/feed to.

Nute burn in late flower I've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

Super soil needs activation?There are plenty of nutrients in my supers soil. However I heard that the problem might be that the soil isnt "activated" is that logical? Thus need to add organic ferts? I am trying this, but I'm sure the super soil has months of nutes in it!
