Looks like iron, but that's only according to the photos on the web. Never had an iron deficiency before.

Yellow and purple leaves
I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

So plants are looking good except for the Blueberry Autoflower, the leaves are twisting & overlapping & most are turning yellow, I know yellow usually means nitrogen deficiency but it shouldn't be with the nutrients it's receiving, anyone have any ideas or suggestions?

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

Mis plantas se están colocando amarillas. Estoy a días de pasar al ciclo 12/12 ya que regué de forma foliar con Big One. En caso de ser ausencia de nitrógeno, como podría resolver la carencia. Muchas gracias por sus valiosos comentarios.
