My tent has been smelling bad like rotting vegetables/eggs/sulpher for like a day. I just noticed these patches on my biggest plant and the smell almost seems to be coming from the leaves? What the hell is this, i can't even identify it? I thought it was my c02 bag... but it smells fine and the soil smells fine. I just watered them a few days ago decently heavily to remedy the nitrogen claw. Kinda seems like phosphorous deficiency, but what about the smell?

Have they been sitting in water?

No, they are elevated on stainless steel grates i had custom built and drain into platters. I just noticed the same spots on another plant. They seem to have appeared out of nowhere today. Only on the top fan leaves, i noticed the smell the day before.

My guess without seeing it is a buildup in the soil from your feeds. The spots could be from a lockout do to said build up. Are you feeding everytime? Have you been feeding for a long time? Do you run straight water or add and kind of life back into your soil?

Nah I haven't given them nutes in 3 waterings because they have the claw. I probably should have gave them some last watering. Could be a deficiency.
 
Smell seems to be going away. I turned the humidity down on my AC Infinity so it runs more often, and sprayed with cal mag last night before lights out... so maybe calcium deficiency. Next watering will be a normal feeding so hopefully the spots stop appearing... weird. I'm almost wondering if the humidity spiked overnight and the leaves were wet when the lights turned on... literally just on the left side on the two plants.

It has to be water burns because it is only on the top leaves... the leaves were probably sweatin and dripping with water when the lights came on. Lesson learned i guess. Gotta keep that air moving! It's hard to diagnose because it looks like a calcium deficiency, just being on the top tells me they got burned.

It's all good now fellas, no root rot or deficiencies. Those leaves were the only ones that had spots, water burns
