Hello,

We are new to growing and we are growing indoors hydroponically. We noticed 2 days ago that we have what we believe is PM. We tried using Seranade but it didn't seem to do much. We read that you can spray with a concentrate of 3% hydrogen perioxide and water. We are in the middle of the 5th week of flowering. My question is if we do spray with the hydrogen perioxide, should it be done with the grow lights off, and if so, should it be done just before the lights go off or before they go on? Will the lights burn the leaves if they are on before they are dry?

Need help with this one asap.
Thanks
Beverly

I have had a thriving garden for years. All kinds of plants and I have not had this problem before. Before I start, at this stage I did not use anything but lighting watering and good soil, no NUTES.

Anywhoo. I decided to a more "fun" grow. I had a 2 sprouts (not sure of the species,the seeds came from a bag of okay reg). I started with training the plant young like most other indoor plants I have grown. They were about 3 1/2" inches tall one had six leaves and 2 staring to poke up, the other 4 leaves that seemed to be getting wider. They were all beautiful dark green leaves and next to ZERO stretching (thanks to a CLF/ LED combo lighting). My temps were stable 78*F and PH was right around 6. All was the same since the seeds were planted. In the matter of one after noon both looked like wilted lettuce. I did notice for some reason the CFL was running warmer than usual. but just turned it off about 2 hours earlier than normal and left the LEDs on. the following day I let the plants run under the LEDS until I got a new Bulb and when I pu them under the new lamp one ended up withering over night and the other is just hangin in.

Are there some strains that are this picky when in comes to temp? Could the lighting and temp changes have stressed them that much? I have some small pepper sprouts under the same lighting hood that were not effected. I'm kinda lost. I was hoping to have a fun simple grow but this is frustrating.

Life is to short to stress over these guys too much but any help would be much appreciated so I can prevent this from happening in the future.
