Just put plant into bloom 1 week ago. The feeder leaves main vein is brown and leaves are starting to drop off. The feeder leaves are from the middle down being affected. I beleive this is this is a potassium deficiency? Sorry waiting for a camera to send pics.

Thanks for that link I have read the info. But still have a question on one section.

Here are a few pictures of ph spotting before nutrient lockout occurs. The last pic is shown is high ph with the twisty leaves. Note the edges are brown, this is a potassium deficiency that is caused by ph lockout.(Sometimes this gets confused with a nitrogen toxicity, so always keep your ph in check and test it often!)

Do I need to add potassium or flush for two days and then add potassium?

if you are having a PH problem, DO NOT ADD ANYTHING until youve fixed your ph issue. because with the ph issue, no matter how much of what you put in there it will not do you any good, but just the opposite. because its been locked out. if you suspect its your ph, fix that. then add what your plant is deficient in.

I have checked my notes and i have had the PH for the plants right at 5.8 - 6.0. Would this range cause ph spotting and nut lockout?
