Is it on the leaf itself or is it a layer on top of the leaf?

Does that look like an early deficiency?Hi everyone, what ya thinkin'
What kind of deficiency could that be?
My bet - potassium.
last portion of water was ~6.2 pH
I wasn't feeding her nutes for ten days by now.
Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.Leaves. Veins - yellow between

Is this a symptom of spider mites or something else?Is this symptom caused by spider mites also, or is this a different issue? There is pale green/loss of color along the veins of two leaves. I’m aware of my spider mite problem, but want to know if there is another issue or just more symptoms of the mites.Leaves. Veins - yellow between

I’ve got a problem but not sure what it is. It appears to be yellowing in the leaves, maybe a magnesium lockout despite me adding magnesium and calcium. I had the same problem with my last grow but it’s much worse with this one. I’ve checked and calibrated my ph pen. Im blaming the soil which is Biobiz light mix. Please see photos for week 4 and tell me what you think. Thanks.Week 4

Yellow centre veins fan leavesYellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?3y ago

Yellow stains on bottom leaves (indoor grow)On day 25 yellow stains have appeared on the bottom leaves of two plants (critical 2.0). We don't know from what these stains are coming.
On one of these plants, some leaves have also started to develop white dots. Spiders maybe ?
Thank you.Week 4
