I thought it was low potassium but its getting worse

I had a similar problem a few weeks ago. It took me a while to figure it out, but I think I'm on the right track.

I think I had a pH spike and it was locking out my Cal, Mag.

Just my 2 pennies. Good luck.
 
U need E/c meter to....
Ph between 5.8 and 6,0 is better for plant
And uhave nut burn ....U have to flush them then start at middle
 
get some ph down and flush your plant of all the nuets and give it str8 water for a week1/2 good water my man
 
Just FYI... over fertilisation of the medium causes a K deficiency. high slaintiy blocks the passage of K... ergo, high fertilisation = K deficiency.

that you clearly have. what concerns me is how you got there... is it over fertilisation or is it under fertilisation. That is the question....

Usually in an over fert situation the plant should be virtually free of red stems and the leaves should be a rich dark green. the only damage or discoloration we should see are the large fan leaves going necrotic from the edges of the leaves inwards. What concerns me with these pix are that I can see what appears to be plenty of red stems and the leaves are not as rich green as i'd expect. this is because nutrient formulas have pretty good amounts in them, fairly spread around. this makes over fert easier to spot.

what nutes do you use and how regular do you feed, etc?
 
KBOSWORTH hasn't said how he is grow or did I miss it?
If he's in dirt 7 is good. I betting it some miracle gro issue?:lol:
