Thanks for any help
Looks like Downy.
Doesn't look like mold to me
Are you applying any foliar sprays?
Does the water bead off/on the leaves? One drop per how much water/solution? That might not be enough. And are you spraying with the lights on? Not enough wetting agent/surfactant + spraying with lights on = burns. The spots really look like water droplets where the water would 'bead' but not run off, hence, burns.I did look under the leaves they don't have any sign of fungus or anything else, I use 1 drop of Dawn dish soap in foliar sprays, I will read up on Downy Mildew that just might be what this is.
A lot of people use dish soap as a surfactant. Soap is a surfactant that breaks/lowers the surface tension of water, thus coating the foliage more evenly and reducing or eliminating the 'beading' effect.And may i ask why do you add dawn dish soap to your foliar sprays :confused:
Water alone is not phototoxic, so if what we're observing are burns they would only be due to something like, say... CaCl.Does the water bead off/on the leaves? One drop per how much water/solution?
