A 4x4! Dude your light is definitely the problem! No way a 100 watt light is gonna be enough. A true 300 watt bar light would just get the job done. When looking at Amazon lights start with lights with 4000 in the description. Your light is xx1000, you need xx4000 or higher. You say your plants are in flower? Here's a plant going into flower today. See the light up there? $539 of not enough light for the tent size, will blow your light out the water. And still not able to handle a 4x4. Not even close. You can buy cheap everything, but not a cheap light. By the time you grow, dry and cure you have 4 months of busting your ass for what? Low yield, low potency, possible bad taste. You may think the light is bright, but your plants will grow in a window sill. With enough light the plants don't stretch cause there getting enough light. The average foliar spray is food safe, not smoke inhalation safe. Plus you don't want to taste it. Avoid spraying anything on a flower plant that you may ingest through your lungs. It's safer to smoke the bug! It's ok, smile and laugh with me. You'll get it in the long run!
