need help with outdoor plant

hey all, I have been growing a nice lil plant of some white widow. I planted it on memorial day and it is has been budding pretty nice. I am growing it in my backyard ( I know not advisable but i have a script, so no worries of getting busted). But my neighbor started leaving his backyard light on and my plant has been making a severe DECREASE in trichomes. Last week my bud was nice and frosty and now not so much. The buds are about 2-3 weeks away from being done. I now am putting it in a dark shed at night, and am giving it a 8 light 16 dark to help it get into a budding phase if had reverted to veg. My question is can a litlle light from over 50 feet away make it go into veg. and will the 8/16 help or make it go hermie? Thanks

so the plant is already almost done and showed sex along time ago! cant turn Hermie, unless pollinated. your plant should do just fine, you should post some pics too good luck

I have seen ALOT better results in the last 3 days. But some of the larger leaf tips are turning a rust color brown. I last gave it nutes on 9/21 and started the flush on 9/24. I plan on harvesting it on 10/4 with the full moon. But what should I do about the obvious deficiency problem as I am mid-way through the flush? and it never should ANY problems before the flush. Could flushing it be leading to an over watering issue? I want good tastingf smoke and don't want any nute build up on the roots. I was also told that putting into a dark cycle for 3 days straight before you harvest is best, should I continue the flush durring those last 3 days?
