Light green "splotches" on leavesHi,
I've noticed light green "splotches" on my leaves which I'm having trouble matching with images of leave problems. Doesn't appear to be impacting on growth and the issue is only visible on close-up so it might just be me being over concerned, but I'd be grateful for advice!

Taken a few pics of one of the affected leaves.
Thinking potassium deficiency but not 100% sure
Was away for best part of a week & had someone else watering them, just plain water (may of spilt on leaves?)
Leaves seem crisp to touch as well as the yellow/brown colouring.Week 5

Deficiency or Pigment?I have strange brown spots appearing all over my top fan leaves at week 7 of Flower. I thought this could be genetic coloring starting to fill in, but now I think it's something more.

Brown spots followed by necrosis on Mandarin Sunset.Any idea what could be causing this necrosis on my leaves? Starts with the spots and grows to crisp up the leaf.
My soil should have plenty of calcium and magnesium. Happened once before on Gelato and never deciphered it.

Calcium deficiency?So, 2 out of 6 are showing this, it looks like a nutrient deficiency, Calcium I'd say.
It's only present in one leaf on each plant, in the bottom.
I've got here CalMag ready to apply, just wondering if you guys agree with me :D
Thank you, and keep it green :D

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!Week 4

Damaged leafsHi guys! I have a flowering Northern Light with several damaged leafs, as you can see on the pictures. Are they deficiencies of some sort? If so, what do you think can be the root cause? I use only filtered water and the RQS easy boost mixed with the soil since the beginning. TY
