Well I think the damage is done, I'll post some new photos in a day or so. I believe the issue had a lot to do with the VPD and the nutes, this is a guess.
The Temps and RH have been all over the place with wild swings in the VPD from .8 to 1.6 in the course of a day. I think I have finally dialed in the correct VPD at 1.25. What I really noticed was that when I hit on the 1.25 the smell of the plants increased dramatically. I have been reducing the light level as you recommended a little at a time and now at 80% working toward 70%. This reduced the temp in the tent by 2 degrees at peak sun loads on the house, 84F to 82F. I have changed the air direction to provide cooler air to the grow room that has reduced the tent temp to 78F. Of course with the reduction of heat I could reduce the humidity from as high as 68% to 62% The outside temps are in the 90's and will be for a while. I'm watching this closely. I hope this will get me the couple of weeks I need to cross the finish line. If not I will just have to take them out early. I will be losing quite a few leaves.
You mentioned adding Cal-Mag. Do you have a brand you like? How much would you have recommended that I add if I had it? (For future reference). I looked at Cal-Mag and there sure are a lot of choices there. Thanks.
