Browning tips

[wanna be dagga kop]

Aweh,

So my one plant is starting to turn brown on the tips on and I'm sure its not nutrient burn, could it be  a potassium deficiency and how would I be able to fix it?

If its not potassium deficiency please help me identify what is wrong.  

Thanks in advance

Aweh, 

It does look like something is not right there. Many deficiencies etc are allready 7-14days in the making before you, the grower physically see them.

You'll have to give more info, like what grow medium you using, what nutes you feeding and how much. 

Tip burn is usually an indication of too much feeding, the shiny sheen on the leaves alao doesnt look right. Possibly a lockout.

@Bos aweh, so at the moment literally only doing 2ml fishmix and 2ml in 2ltr bloom in 2ltr but thats on all my plants n this is the only one that looks like this.

It is in a coco perlite mix, i also thought it could be a nutrient lockout/ph issue. I'm just not sure what to do at the moment because i did do a flush as well but i'll have to wait and see what happens .

I grow organic in my own soil, have used coco for cuttings but not for full on growing. Coco should be buffered with calmag to avoid issues later on. 

Pretty sure one of the more experienced coco growers may shed some more light on the issue.

You are using the wrong nutes for your medium...or you need to add something like explogrow to your feeds to introduce a micro biome.

With the current nutes you are using, you should only.be using the fish mix or grow(I prefer grow). Start adding bloom only from the 3rd week of flowering.

It does look like you have a potassium deficiency, but it's more than likely due to major pH issues causing a lockout than a lack of potassium imo.

No need for bloom till end January for photos outdoors. The difference between Grow and Fix-Mix is that Grow is 75% Fish-Mix and 25% Molasses. The sugar isn't needed by the plant till flower.. but can help your micro organisms in your grow medium, I prefer to go Fish-Mix for veg phase and swap between Fish and Grow once they reach pre. 

Give the plant with the brown tips a flush with 30 liter water. Then let it dry up and go back to add 2ml Fish-Mix per liter you apply. When your plants go pre, is the first time you can add bloom, not before.
