How does my grow look?
Thoughts on my babies? Nute deficiency? Light burn? Over watering? pH off? What are your reflections on how they are looking now?

Super Yellow Leaves in Mid/Late Flower
Does this bottom left plant need more nitrogen? The last two waterings we've given it 1.5 ml/liter of Micro. Should we give it more? The other 3 plants of the same strain are much smaller, much darker green, and further ahead in flower. These Blue Dream autos are 51 days old.

They say yellowing is normal, but this much?
Not sure what to do. First time with autos, and they're around 69 days old. Breeder says 60-70 days mature. Used living soil. The yellow has climbed both plants yet the trichs are only 15-20% amber. Will my girls be okay? What kind of TLC can I give them until harvest? Noob here

Discolored Older Fan Leaf
I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?
