Sodium shock under gavita 750s

[rolandblunts]

I've been growing 12 plants under 9 gavita 750's. I put my vegging plants in this room with the intention of growing them for a couple more weeks before flipping them. My sativa plants seem to veg extremely well under the gavitas set to 400 watts. My indica plants, on the other hand, seem to experience heavy sodium shock. Growth is stunted and the stems turn red. Has anyone else experienced this and what can be done to get these plants to take off?

Foliar feeding with kelp or humic?? This is what's normally recommended but I have used plant magic cal-mag with some grow as a foliar feed in this situation & found it helped the plant recover.
