When do you STOP spraying plants?

I lightly spray my plants every other day. When do I need to STOP doing this?

if you are doing this, you should STOP when the buds start forming.. spraying when you have buds will greatly increase the chance of bud rot.. humidity during flower should stay rather low..

Most foliar feeding regiments will allow you to feed up to week 4 of flowering. You want to mist the plants instead of actually spraying them, try to avoid the larger flowers and focus on getting the fan leaves. You can spray an hour or so before lights on by creating like a cloud of mist above the canopy and letting it fall on to the plants. Raise your lights up to max height and then you can lower them about an hour after they come on...this will aid in the drying of any residual spray and prevent burning. Optic Foliar makes a 3 part spray that you can use with lights on. OPTIC FOLIAR LINK
