Someone with some knowledge please spray with it lol, I cannot find out what is causing this. I have not fed them any real food. they have been vegging for 4 1/2 weeks and have given them some teas some superthrive and roots excelerator.
It says you 'don't see but are spraying for bugs', does that mean you spray the actual plant? or just the soil/area around the plants? Depending on what you are spraying with (or if you are spraying with lights on) it might be causing the damage to the leaves . A little more info might help everyone (type of soil/light used/bug spray used/etc.)
Sorry I don't have much knowledge to give
** EDIT ** looks like someone got here while I was chasing my kid
Foliar spray (organic or not) can cause burns due to lights being too hot n too close. What light are u using n how close to the top is it. Also a oscillating fan can help dry out droplets left behind decreasing odds of burning!
