Calcium deficiency?
Hello everyone, I need your help once again. I have just spotted some brown/yellow dots on 2 leaves of my plant. Did some research and looks like Calcium deficiency, but still wanted to ask you. If that's a Ca deficiency, should I add CalMag next time I feed her? Thank you ✊

Zu viel Dünger benutzt?????
Pflanzen hab ich glaub ich überdüngt sollte ich bis zum drain warten mit nur Wasser giessen um den Überschuss in Griff zu bekommen oder direkt reagieren und spülen??? Erkennbar an den Blätter rändern, die Zähne klappen sich hoch, oder bin ich falsch?

Plant growing weak (leaves); don't know what to do / to expect with her
One of the plants I'm growing is looking feeble. Leaves are growing thin and she drinks less than the others. Same strain and same growing conditions. Seedling was stuck in his seed's hull and I had to remove it myself, scrunching a bit one of the cotyledons. What should I do ?

Deficiency ? Chlorine from tape water ?
Spots appeared after last watering, 4 days ago. It doesn't seems to evolve to more spots. Using basic gardening soil. Chlorine in tape water X 4 those days, because of covid-19. So if not a deficiency, might be Chlorine ? Or Chlorine killing life on the soil? Suggestions ? Help!

Krank oder verbrannt oder nur angeeckt
Was könnte das sein? Es gibt im Zelt keine Insekten oder so. Dünger nehme ich die Hälfte der Angaben und die Lampe ist 70cm entfernt (höher geht nicht Zelt zu klein)

Wavy leaf and light green speckling
La Bella Afrodita, Auto. At 16 Days. Slight waviness to the first set of leaves after the cotyledons. And, light green speckled pattern on first fan leaves. Anything to worry about? What causes this? Plant seems healthy.
