Do you give nutrients? I'd recommend checking pH and EC if you do, as there are clear signs of deficiency of (probably) immobile nutrients like Sulfur or Calcium
@Zazalamander, no i dont give nutrients but i use my own soil and give them fresh soil when they need, She is good, she is full organic like all my ladies and the only problem i had was that i watered late, the soil on top was dry and the bottom was wet and my co2 was running out, now i got fresh co2. I like it for the taste and the quality that my plants eat themselfe slowly and are not full of nutes, i grow now for 10 years and i know what i do but thanks for the info mate and i hope you will make your first report soon!
