Early nute burn or normal?
I apologize if this is a stupid question... I'm brand new What is your guys opinion on this slight discolouring in the centre of the plant. I'm not sure if this is a really really early nute burn, or if it's just a lack of Chlorophyll

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?

Yellow leaves at the bottom
Some few leaves, two older and two new ones, turned a little yellow. All of them on the bottom of the plant. I don't know if this is a normal development or perhaps Na deficiency? It's my first grow, so I don't have experience. Help would be appreciated.

Deficiency or light stress?
I start by saying that the light was not close enough to cause stress imo.. was about (30cm) of distance from this plant. it seems that it is more a deficiency in my opinion but I don't know exactly which one.. What do you think about that?

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Help validating what this is
My plant seems to have developed some kind of deficiency/excess. I researched and think that it's CalMag deficiency, added CalMag to my nutes (1ml/l). Just wanted to check in with the experts here to get a second opinion. The growth seems slow I'm afraid I may have stunted her 🤦
