Help please!!! Mold???

My garden was absolutely beautiful during veg, started flowering this week in subcools super soil w ph at 6.5. Temp 70-80 day and night. Has an exhaust fan and 10 inch ducting so plenty of air flow. Humidity is near 0 as I'm in the desert but I do not most or humidify. In a closet about 4 feet by 4 feet by 8 feet. All of a sudden this morning a few of the plants looked like death under the fan leaves so I trimmed that all off and organicided/neemed the whole garden and rinsed it off lightly w 6.5 ph RO water. This afternoon the fan leaves started developing some rust colored spots and curling and ideas!? Pics below thank you!!!!!

They were well established in this soil and you didn't feed them anything else? You composted the soil for a good month? How long between spraying them and rinsing them? Sprayed under hot lights? Your adding cal/mag to your RO water?

Kinda strange from what you describe so just poking for more information...

No sign of mold or mildew imo.

Looks like a deficency. Need more phosphorus in flower for one thing.

You may want to consider that your soil is getting depleted too.

Humidity near Zero is pretty much unheard of.

Plant does not look well and pics 1 and 4 (especially 4) looked cooked by fertilizer.

Hot dry air can make overfertilization a more significant problem. It's all about excess salts in the soil and osmosis and the plant losing (transpiring) more water than it can take up.

Desication.

I didn't think you could have this problem (toxic salt) from a properly prepared organic soil? Is that a myth? Compounded by low humidity makes sense. Very interesting!

I used subcools super soil not sure if you're familiar w it but I don't believe I can be over fertilizing with it

Flushing would probably help and then feeding it with half of your normal amount of ferts and hope for the best

Yes, I've grown in it before. Yes, you can burn a plant with it easily by not composting it or transplanting a rootball grown in weaker soil directly into it.

thanks guys turns out the a/c was randomly going off while I was at work, go to 101 when I replayed the camera I have in there, all good now. ive never had mold but also never over heated my ladies before either. I appreciate your feedback

Glad you figured it out! Good luck!
