2 of them have major catching up to do. will not effect when i put them into flower though, no matter what, they get until feb. 1st before flowering. quick question, i'm running through veg. with a 400w MH, how much would it decrease yield if i were to stay with the MH through flowering? just don't have $110 to spend on an HPS at the moment. i do have a friend that is contemplating letting me use his 360w HPS, but i would have to put off flowering for another 4 weeks, or until he finishes flowering. any suggestions?
