Take those big leaves off there straining your plants, they need watering, the drooping is evidence of that.. The best way to adjust to new light is put them in the new light for half the time per day after 3 days try full Time under new light.. I would place in the tent under the canopy of veging plants, in the shade almost then move into full exposure.. I'm just not sure how powerful you lights are but they will be fine if the lights not too close..
