HAHA man thats funny, you have your bro living in your grow room....
If those pics above are what your worried about then stop, they'l be fine, yeah you may affect to overall yeild by frying them a little but ive seen ten times worse than that.
Recently a friend of mine who didnt want to invest in a real timer despite my insistance fried the shit out of his, his lights stayed on for 3 days and due to inadequate air exchange temps went up to 137deg f. When i saw them every leaf had dried to a crisp and were crumbling and falling off. Every fan leaf dropped off and his bud shrivled. It came back to life though. Obviously his crop and yield suffered but they lived to finish flowering.
As for the herm, couldnt comment.
Happy smokes
I'm hoping it's genetics and not a ph issue lol either way im confident i will still pull in between 10-30 oz from the 10 plants by the end of the month. I'll upload more pics when the lights come on.
