Taco Leaf Big Time Help Plz

Hey everything, thanks for the opportunity of helping me on this issue here. So I'm growing Haw. Skunk in a hydro set up ( deep water cultivation ). I've done ebb and flow but this will be my first attempt using a closed ventaliation system using C02 with deep water cultivation. I'm aware of why they fold like a taco but every change I've done hasn't shown any progression. My temp is usually 75-80 (72) as we i wrote this, humidity is around 55 but has been increasing due to the leafs transpiration which has now hovered around 55-65 but i have a fan on a timer that brings fresh hair on the hour for 5 minutes which brings it back down to 55. My light is a 400w and is normally 1 and 1/2 to 2 feet away from my plant. As for Mg I'm using FloraNova which has 1.5% mg and added a secondary additive knows as Cal- Mag which contains an additional 1.2% mg. I'm adding some photos to see what you guys can tell me. Also just as a heads up the pump into each bucket admits alot of air when i remove the cap with the plant think of it as a little hot spring where you see the water bubble up as a small mountain. Would that have any affect? or is it okay leaving it that way?

Another note to the first message. My ph level is usually 5.8 -6.0. Lately I've had it 6.0 so that it can absord more of the mg and nitrogen.

Does anybody have any idea's or suggestions? I'm seeing reviews but no replys....? Nobody has ran into this type of situation?

Not sure if this helps...when my plants start to go into flower they for some reason need a higher PH. I use a little peat moss in my mix and any fert I give it has to be mixed with baking soda or something to keep the ph up high. 7+. If your desperate give her a good soda soaking and see what happens. Hope she comes back from the taco problem.

Next time I'm checking the date of post
