Two out of four plants are still being very yellow. What could this be?

3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.

Nutrient deficiency
What kind of deficiency these leaves are showing? Can this be lack of nitrogen? I am using a lower amount of BioBizz Grow these days (1ml/L), passing to BioBizz Bloom and Top Max as they are in the middle of the flowering stage. In case, should I integrate with more BioBizz Grow?

Discoloration continues
Pattern seems to be progressing. Brewed molassas tea with alfalfa, kelp and worm castings. Spots worsened so I treated with CalMag last night. Thought I would post to see if I could get your thoughts.

Strange leaf shape, who has encountered this and what came out as a result?
1. Am I right that it was just overwatering? 2. Who has experienced the same thing? 3. What are the chances of growing a healthy plant? I appreciate all the responses, this is very important to me, thank you!

Autogrowing
Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.
Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.

Deficiency or Genetics
Would you guys guess the yellowing on these leaves is more natural coloration from genetics or do you guys see something more? Plant is definately small but seems to be healthy and buds keep growing.

Lowest leaves turned yellow
After a very hot and sunny day (about 37°C) I noticed that the lowest leaves turned yellow. Is this a sign that I should use more Terra Bloom? If so, how much more should I use?
