I'm 22days into flower, and my plants suddenly developed these burns/spots. When I watered last night, I'm sure this wasn't there. Here's some pics of upper leaves I culled:
And heres a bottom leaf for comparison:
They'd been getting a little pale on top, but I figured it was from being too close (~12") from the 1K's. I run water-cooled lights, and sometimes forget to raise them enough as the plants grow. I noticed the spots today when the lights came on. That's when I realized I was only 12" from the light. I've raised the light to 2' above.
FWIW: I'm running h&g coco's line, ~1.6ec, ~5.8ph. I use ro water, and add .7g/gal epsoms for Mg.
I'm thinking this is just from condensation (from watering last) night, coupled with close lights. However, second opinions would be appreciated.
