I check my phone each and every time I water and feed . Molasses feed the micro organisms in the soil , and helps you trichomes to get oily . Have you ever smoked and when it burned , the end of the joint or rello would be real brown and oily like Sapp. But yes a longer dark period help builds more crystals , and the plant drinks more water , so it helps to dry out the soil ah Lil faster , I’ve read where the longer dark period cause the plant to go into some kind of safe mode , and it produces more trichomes , I don’t know the science book terms of what , but I have experience it in my last 2 grows and it do helps . You would have to take a before picture and after to really see the difference , are you will notice it right off . If it stopped , than its was because of the PH swinging to low to fast , and if you got it back where it needs to be, than yeah the plant will begin to thrice normally . We glad you got it under control quickly , before it could of been costly to your yield .
