Looks like a magnesium deficiency to me. Some of the pictures from last week it looks like there is some interveinal yellowing and the deficiency has progressed. Epsom salts will help fix the issue. Happy growing!!!

Nutes too early?
The leaves of my northern lights look a little brittle and discoloured, maybe the small amount of nutes I gave were too early?

Copper/Dark purple dying leaves
Weird copper/dark purple colors on greenhouse plant leaves. Do any of you k ow what type of deficiency/ toxicity/ root problem this can be ? Closest I can think of is Phosphorus deficiency but I cant pinpoint it. Any help from someone who might have experienced this will help🙏🏻

Hydroponics, i need a second or third pro opinion. Just a Deficiency? bad pH? (I alreadt did a partial water reservoir change tho)
Yoyoyo! If someone of knowledge could help me here, I would be grateful So I think it's a Magnesium deficiency, caused either from my too low pH (5.2) or too much CalMag (only used 1,5ml on 10L) I gave a more in-detail description on my diary. lower leafs are "crispy", not smooth

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?
