Ozone damage

    Hello everybody!
    I have been doing a grow in soilless (ProMix) with home-blended salt ferts. The strain is Nirvana "White Widow" feminized. I flipped them to 12/12 on January 19 after arriving at a good-sized canopy for my tent.

    I encountered an issue a few days ago that stumped me until I had a facepalm moment.


    I'd repositioned my ozone generator to send its hot little stream directly into the room containing the grow. i did this one time and must have exceeded the toxic limit for one plant, which developed the sort of leaf damage that could fool one into thinking sudden cal/mag issues.

    Here are the pics of the affected plant/leaves. I'm posting this as a reference to a problem not often encountered. cn

    These pics were taken on Feb 02 when I noticed the damage. HPS light.

    These three were taken today in sunlight. The first is backlit from the underside. The second is from above. The third shows a leaflet in detail.

    I run a cap ozn1 outside the rooms but the air does get circulated and drawn back into the room. Just not directly blown into the room. I'll keep an eye out for this.

    What kind of generator are you using...
