Ok, guys yesterday I bought that spray that kills the insects, it works but I think I over spray the plant because today morning the tips of the leafs were burned can this be the problem?
It doesnt hurt to turn the lights off a few hours in vege, so next time spray, turn off lights a few hours and let the liquid naturally disapate a while, then swithch them back on. The liquid droplets magnifies the light.
If it is just the tips, yes, leave them be. but, if you have ones that are worse. Then I dont agree. If a leaf is damaged the plant will try to repair it. That's alot of energy that could be used for new growth. I would pull the bad ones off in a heartbeat.
