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?

Any idea why the leaves are curling inwards like they are in the last two photos? Is this because it's too hot, or am I giving it too much water? Should my fan be blowing on the plant itself, or the 150-watt light? Thanks.
