Burned leaves and buds

I sprayed my plants with potassium bicarbonate early this morning and now most leaves are burned and bud hairs turned brown. I still have a few weeks until I harvest. Is there anything I can do to save the plants and buds?

Wait it out.. afaik you never want to spray during lights on or day time (if outdoors) or you risk burning your plant as the water magnifies the light/sun.

That's an old-wives tale and if true, my outdoor garden plants should be covered with burn marks.

Try if for yourself, take a hose to your plants on a sunny afternoon and see what happens.

The water droplets don't maintain their spherical shape and the point of focus is not on the leaf. Water is also a fantastic heat sink; even if the droplet shape was focusing light to single point on the leaf, it wouldn't generate enough heat on the leaf surface. The only exception is that some hairy leaves can potentially "suspend" a water droplet at just the right distance above the leaf which both focuses the light on the leaf and the water can't cool the leaf since it's not making direct contact.

The primary reason to avoid watering/spraying mid-day is to minimize evaporative losses.

What ratio of potassium bicarb and water did you use? I burned some hairs last year , I assume because I was mixing too much PB. I've dialed it back to 2-tsp per gallon, seems to be working good this year.

Nothing you can do to reverse the damage though. Just hang in there and prevent further damage.

I think I probably used too much pb. I used a little less than a tsp with with my spray bottle. Thanks for the info. There's always next year. If it turns out to be unsmokable I'll turn it into butter for baking.
