Do these random spots mean nutrient burn/deficiency, or is this normal?
I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Hi Growmies, I have some drooping to the edge of leaves and discolouration. I've been watering every two to three days and live in a soft water area. Is this due to under or overwatering or is there possibly a nutrient deficiency. Thank you ✌️

The yellow spots that were seen last week have multiplied and started to appear on newer leaves. I should mention my tap water E.C is 0.8 so quite high. I still however added calmag this at it seems to look like a calcium deficiency. Are they to young for one though? Thank you

Hello, There are copper coloured spots on many leaves on one plant. I have tried Foliar spraying with magnesium. But it doesn’t seem to help. There is a bit of purple in the stems as well. I gave them some cal-mag, but still there. A few fungus nats. Gave nematodes 2 days ago.

Little browinish/beige dots near leaf veins
I noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?
