Hi! I just bought an albo and it’s been watered once with silica mixed in to prevent browning. This is what the normal lighting setup looks like - second picture (thai con is where the monstera albo is now). three grow lights about 8inches away from the plant. Lamp 1: box says output is 800 lumens and energy used is 8W, Lamp 2&3: say 10W each. It gets about 10-12 hrs of this light a day. I get about 2-3 hrs of direct morning sunlight in my window and this plant is put in front of that window then moved to the lighting setup for the rest of the day. This morning it was a bit foggy before I left (so I’m not sure if any sunlight came into the room) and I was out so I didn’t get a chance to move it from the window to the lighting table until about 5PM. When I came back, it had developed the brown spot as seen in the first picture… Is this due to too LITTLE sunlight today or too MUCH?
