Hey guy seems like I am getting rams horn on mainly my SD strain. I am at the start of week 2 of flower and just did my water change today. I am running a DWC Bucket system under 10 1000w sodiums. Pictures are included but not sure if you guys can see, I have no clue why my iphone is getting these black bars. What could be causing the folding of my leaves? My current Ph is 6.0 and my EC is 1.6 I am using mainly H & G with Calmag and Open Sesame, stopping this week. Also, when the lights go off the plants droop but perk back up about an hour before the lights come on.
