Hi, i think i am having a deficiency with my two plants, During veg growth some of the lower leaves show yellow spots and some brown spots and it's starting to creep up to the top leaves.

Also the leaves have been twisting and canoeing, especially around the smaller bud sites to the point where on one single leaf of a fan leaf will completely twist upside down.

Any ideas?

Pictures attached

Thanks.

Do you really want some one to answer all the questions before the question you ask or are those just for you?

It looks like Iron or Mg you need
