Greetings,

I have 84 plants, 64 i am flowering (for 3 weeks now) in sog, and the other 20 are being vegged.

I started noticing some powdery mildew on the lower leaves this week, so i googled how to get rid of it and decided to go with the baking soda + water solution.

I mixed 1 tablespoon of baking soda (sodium bicarbonate) with 1 liter of water and sprayed the leaves of the plants.

The next day all the plants were terribly burned, with yellow spots, loking as they were exposed to too much light and heat.

I just dont understand how this could happen from baking soda.

Anyone?

I believe it is 1tbs per gallon of water, not a litre.

Agreed, but still, how can sodium bicarbonate cause this much damage? Its only 1% solution of baking soda in water..

A tablespoon in a liter is not quite a 1% solution. It's closer to 2.

I get your point though.

People here really seem to like the milk alternative when it comes to powdery mildew. I've been lucky enough to not run into that one yet. Most of my malady's are self made, lol.

Sodium in high quantities is toxic... if you didn't cover your medium, you probably poisoned the rhizosphere.



Personally, because it is sodium, I would avoid using it.


Vinegar would have been a better choice, IMO.

Probably catapulted the pH momentarily as well. If that's organic it should work itself out if it even affected the soil at all. Wash off the leaves, though.

I killed a flowering plant with baking soda, overnight. It really put me off spraying anything on my plants at all.
