What’s wrong with my plant? The top leaves look spotty. Could it be the coco coir pot?

You need calmag, I imagine. Or you have a severe lack of micronutrients like iron, sulfur, etc.

help! my plant is turning pale. the green color is losing.
the green color is losing. some leaves burn from the tip to the stem of the leaf. Excess fertilizers (because I fertilized the soil) or deficiencies due to few nutrients? I also thought that it can burn with nearby lights, but the ones that burn are far away

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.

Halb gelb, halb grün
My plant is currently showing slight potassium deficiency. But somehow only on one half of the plant. The other half looks well-fed. Can someone explain this to me? Like, why doesn't the deficiency affect the entire plant?

Yellowing some leaves
One of my plants(Quick one RQS) is yellowing some fan leaves. Is she just killing of them because she doesn't need them anymore or Is It some deficiency? The plants look very healthy.

Did I give too much fertilizer??
So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Vexatious yellowing I can't get to correct.
This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Small yellow stains
Hello colleagues! Would you kindly help me and tell what these yellow stains may be caused by? I think I could set the ph-level too low, so it may be a deficiency of some nutrients, but the plant seems developing normally.

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?
