Since you have solved it, I allow myself to ask if my problem was calmag heat too? https://rollitup.org/t/dead-spots-on-lower-leaves.1000248/#post-15165460

Hello mate it's looking like a call mag or something. I would say not heat or light as it's on the lowest leaves and mine was just on the very top. Hope you find a solution mate
