I'm starting to notice yellowing of leaves almost daily now on a Critical XXL scrog grow. She is 5 weeks into flower, had a rough (cold) start, and has always been a bit stunted. I was worried I'd overfed (3ml / l biogrow) so scaled back for 2 weeks. Is this normal?

Yellow/brown marks
My plants are becoming more yellow and now also showing some brown/yellow marks. I'm afraid it’s because I may have splashed some water containing a little bit of CalMag on them one time, not knowing better. Might that be the issue here? And most importantly, what should I do?

Leaves still goes yellow after flush with pure water 6.5pH, then only water with Biobizz Fishmix and last time all nutrients but 50% of recommended.
After last question with those symptoms, I flushed her with pure 6.5pH water, then next time started to adding only Biobizz Fishmix, and another next time I started to add all nutrients again but 50% of recommended. Buds, the white ends of the flowers begin to turn brown as well.

Magnesium nutrient lock out, triggered by too much potassium ?
@Burmese Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉

Yellow parts of leaves.
Anyone can suggest what kind of problem is on the photo - brighter inner parts of leaves. My idea would be that it needs more Magnesium?

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

Iron Deficiency?
Appear to have an iron deficiency, perhaps as a result of lock-out. May have been triggered by light stress or environment changes. Living soil media, watered with rainwater, supplemented with compost teas and organic soil drenches pH to 6.5. Seeking advice as to how to correct

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

Nutrient Burn or Deficiency?
I recently fed her nutes and two days later I am seeing this yellowing on the baby sugar leaves on top buds only. Do I flush? Or is this a nutrient deficiency and not a nutrient burn?

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
