Leaf Discoloration - Hopefully Nothing
I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.

Yellow lower leaves
Hi! I went out for the weekend and when i came back most of my plants had yellow lower leaves. The weekend has been very very hot and im wondering if it was lack of watering or is it a lack of nitrogen? Some in one plant the leaves were dead.

Yellow leaves
Started seeing new leaves turning yellow at the edges on this BCN Critical Auto. I think it's a calcium deficiency based on my research. Would love to get a second opinion and some tips, if possible. Many thanks.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

What's wrong here?
Some leaves turn from green to light green to yelleow almost white. Begining from the edges to the core. Veins turn light green too. Rusty spots appear and leave edges and tip curl upwards. In the last state leaves get brittle and drop. Thanks in Advance.
