My tips are turning brown

Can anyone please tell me why SOME of the very tips on SOME of the leaves turn brown or white?

The tips looking like they’re “burning“ along with the discoloration on the edges of some of those leaves is a pretty reliable sign of a potassium uptake issue. She either needs some more or she is locked up from a pH issue, excess nutrients or some other issue. Checking your runoff or doing a quick slurry test of your soil if you are growing in soil will help your tell which one it is.

Ok..I'll check the soil and the water both..I was told that fox farm keeps the ph pretty much within the parameters

My ph for soil and water age good..I'm growing in a coco soil mix..if it's a potassium issue how do I give her the potassium and how much?

whats in your soil mix currently? anything like macro micro amendments added recently?
are you using the nutrients as per label?

We follow the feeding chart for fox farms..we haven't added any other nutrients...just the coco and soil mix

How old are your plants?
I would just back down a little for a week.
I use FF soil and ferts and really like the Wholly Mackerel.
I actually use it with both the grow big and big bloom through my veg growth.
I stay away from from tiger bloom and go right to the dry trio from FF for flower.

No experience with coco.

Thanks man...were gonna give her a week off...weird situation...found a seed in some really good OG Cush..germinated it and let it grow in a pot in the window sill!! Decided to try growing...she sat looking like a seedling for I'd say 3 weeks..had to tie her stem to a straw so she could stand up!! My tent and lights and nutes came with some autoflower seeds..I've got her (photo period) growing alongside a Bruce banner and a deelite..all 3 are doing good...once OG got under the lights she took off!!!!
