GrischaBXLstarted grow question 3 years ago

Hi Breeders, Elizabeth is growing well, but the bigger leaves are curling up at the edges. I already increased lamp hight and lowered to 18/6. Is it air humidity? Or too much water?

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is? Please help me, I need to feed in a few hours.
