Hi every1 im just new to this I am having problems with lack of potassium leaves are yellow and curling and dying. strain is jack herer using coca soil and coca a&b. I flushed twice over 6 days, I have added half t-spoon of Epson salt thinking it was lack of magnesium. when I reallised it was lack of potassium I read that I should add bloom to my feed and that will help my palnts as its got lots of potassium in it so I added pk 13/14 today so im hoping that works and the plants starts budding again as its slowed flowering its 7 weeks this Friday and it looks like 3 weeks flowering,
I have also being told 2 get potassium sulphate and that would help aswell could some1 please advise me as this plant is the biggest ive grown and don't want to lose it

Pictures would help but with coco potassium is something that coco generates on its own hence why most coco specific nutes are lower in K.

Usually in coco with coco specific nutes people tend to think a Ca or Mg deficiency is K deficiency.

Post a pic and I'll let you know.

Could be that K is at a toxic level causing lockout of K.

Looks like plain and simple Mg def BUT I need natural lighting not under hps so that I can see colours etc.

Wow those pics are terrible.

I know I said without the hps going but I meant with some light though that actually shows the colour of the plants.

Really can't see very much there at all.

But the discolouring that I do see really does look like Mg def.

Once again though a better pic is DEFINATELY required.

If you could remove them from your grow and place them in a well lit room so that I can see the actual colour of the plants.
