Brown spots, serrated edges curling up - calcium deficiency?

bongriplarrystarted grow question 4 years ago

This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

@CraftbyKeMo - thanks for your reply. Limited space provided to ask a question makes it tough, but here's what I've been doing. it's in soil, and I'm keeping the tent tent around 67 with a 60-65% Rh. Tap water pHed to 6.2-6.4, and I'm feeding on (what I think is) a light nutes schedule. I'm giving Cyco Bloom A + Bloom B according to instructions, and I'm feeding 2x/week by diluting nutes into about 1L of water. The rest of the time, the plant is on a blumat for watering. Anything else I can tell you that might help?

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

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.
