opinions needed

Hello fellow stoners! I have a question for those who may know. I run a sealed room that is co2 (1200 ppm) enriched (1000 wt lights). I use ebb n flow tables with advanced a & b and some other additives. My temps are usually in the range of 80(day) and 68 (night)degrees F. But lately the temps have been a little cooler in the day, around 75 F. The question or problem is that my plants are finishing earlier than usual. Around 7 weeks on an 8 week strain. Also had one herm recently and she is typically very stable. Could it be too cold for them during the day??? Any help would be greatly appreciated! Oh yeah and right now im running what the clone man calls big buddha cheese. But it smells just like OG Kush. 30 Days in and the hairs are turning and leaves purpling as well as an over all look of finishing. 100% cloudy so far.

Hello,

-Big Temperature change
-Light leak
-Over nuting

are often reasons plant turn hermies

When you say "hairs are already turning" do you mean they are turning orange already? Are you sure your hermies did not pollinate the whole crop? Was there any pollen on leaves or near the plant? I would try to clean everything and pull that plant out if its a possibility chance that she push more pollen is possible (due to airflow) and you do not want to seed your crop after 30 days. Unless its part of the plan

Wish you a nice day

Yeah I think the problem was low temps while the lights are on. So I cut everything and im going to install a thermastat that will control that room. And maybe a heater.
Thanks!
