LSD leaf problem

[xboxsetupsuck]

I am on my second grow 3 white Siberian and 5 LSD . Has anyone got any idea what it is and how to deal with it. At the moment its only on one of the LSD

do you use any foliar sprays? if so this can be light burn/bleaching from the spray resting on the leaves under the lights.

if not i would look close for pests. look for silvery almost snail trail patterns and small dark dots on leaves. the bugs themselves would be thrips and larvae are very hard to see with the naked eye

You was spot on lights to close to wet leaves thank you.
