1st Grow indoor 4 x 4 tent!

4 weeks in and expecting to see more growth than what it has in terms of leaf and height but both seem stalled. 1 plant especially has been very dwarfed in size compared to the rest at 2 and a half inches in height, the one I featured in the last picture, The bottom leafs turned brown and died (I removed them after taking that picture). 3 of out of the 12 plants seemed especially sick / wilted, from the recent transplant last week I thought the 1200 watt LED light might be too much for them and stressing them further so they were set aside and put under 19 watt LED veg lights 18 inches from the leafs to monitor for a few days with a small fan on low.
