I just can't believe that so much heat was absorbed by that back panel that it fried those leaves like that. And as far as it being so reflective that it burned them I don't believe that either. Fluoros just arren't that hot to make surrounding areas so hot and especially as far away as you have them. I've got leaves laying right on the mylar with 43 watt fluoros right next to it and they don't even begin to burn. And from what HD suggested in a different thread, burning from a reflective surface is not something you have to worry much about from CFL's. HID's yes.

Also I see that almost all the leaf tips are burnt. From what I understand that suggests that you're maxed out and a little over the max ferts the plant can handle. So you might want to back off ferts a little.
Marc Benson Reviewed by Marc Benson on . HST Question is for Zandor or anyone whoâ??s done pruning. H-man? Pics show first grow box with plant 30 hours into SCROGinâ??. Still 24/7. HST?? Yeah. Cause it was like tieing a screaminâ?? toddler into a crip. Heart ached at every tug and pull. You can see by other pics it looks like I should have plenty of room to try a few clones. Will have to rework lighting and put in a partition. Including pic of blower I got for $17. Should work good after one end of intake is taped off. Rating: 5
