Red pattern at the bottom of the leaf
Noticed the appearance of this red pattern at the bottom of my leaf. Could this be attributed to plant stress? The new leaves are very green and healthy, so I am thinking this red pattern is associated with some stress the plant suffered in the early stages of development.

Deficiency or leaves turning red/purple due to flowering?
Deficiency or natural change due to flowering? I fed her additional CalMag and PK so I slightly caused nutrient burn. That does not indicate a deficiency normally. Thank You for any advice!

dying top fan leaves
All of my 3 plants are receiving the same treatment but one of them is showing signs of distress. Some of the top fan leaves are getting dry and brittle and dying. I thought perhaps the problem is I haven't been allowing enough run off?

¿Qué le ocurre? ¿Tiene recuperación?
Las California Kush no acaban de recuperarse. He regulado el pH y la EC de todas las plantas. Una parece que se recupera y está echando hojitas pequeñas de un color sano, pero a la otra le salen muchas manchas en las hojas nuevas.

Plant health assessment (Leaf coloring and nutrition help)
Sorry for bombarding you guys with questions, but it's getting serious now, right? Anyway, my leaves are getting funky colors and I do wonder, what is causing this? Is this normal? I have used the bloom nutes as in my diary once this week, rest was distilled watering.
