Mine came just a couple days ago as I stood over my ladies as they finished their third week of flower. I was glad the stretch was over an it was time to get down to business. I was happy until I noticed only 1 of 2 switches on my lights were flipped to on. I realized I had only been growing with the "veg" spectrum and not the "flower" spectrum. Ugh, stupid LED lights, lol! I switched the flower spectrum on along with the veg so they are now at full power and the ladies much happier. Not sure what the overall effect on the outcome will be, I can only imagine the plants will be slightly smaller than they would have been but who knows. I still cannot believe I forgot to switch them on for three whole weeks of flower. *facepalm*
