What is this, is it mold? I posted some (blurry) pics yesterday and got several diagnoses. Here are some clearer pics.

Also, here is a pic of some discoloration on some of the fan leaves. Any ideas on what is causing that?

Its a hydro grow and about 1 month into flowering.

Thanks Docs

The leaf problem looks related to macro-nutrients... Are you going organic or chem fert? What about your water, what is it's story? I would hit it up with hygrozime or H2O2 to kill the fungus. I'll bet your roots have problems too, can I get a photo of that?

I am using Flora Nova Grow 3 tsp/gal plus Big Bud 4tsp /gal. Sorry I do not have a ppm meter.

RO water?
Do you have a macro nutrient?
I would invest in either 35% H2O2 or Hygrozime for a start.
Your leaves look awfully dark, try reducing your addition of the grow nutrient.

I am using distilled water.
Can you suggest a macronutrient? I thought the Flora Nova Bloom, had me covered.
How do i apply the hydrogen peroxide?

thanks dude.

It looks like something you added to it and it fucked them over. There's not much you can do for mold.:cry:*

The hydrogen peroxide at the store is garbage (3%), but if it all you can get put 1 full bottle in per gallon.

I used Floramicro when I was using the GH series. With distilled water you may be lacking in Calcium or Magnesium as well. I know with RO water I was, not sure about distilled though. Maybe someone else will chime in on that.

My assumption is that I drain my resovour, add hydrogen peroxide and water with NO nutes. Do I go with that for a week, until condition improves, til end of grow?

thanks

H2O2 is compatible with chemical ferts like GH 3 part. You can run it every change. Some people run it through the entire grow regardless of needing it or not, it keeps things clean and healthy.
