Lower leaves drooping after transplant to coco from seed starter soil

My friend just recently transplanted a well rooted 10 day old plant that was in a 12oz seed starter soil cup to a 1.5 gallon hempy. (70/30 coco/perlite on top with a perlite reservoir) He had done this before and had no shock last time. This time, the lowest leaves and the first set of true leaves look kind of droopy. There is new growth but it is slower than it was in seed starter soil. The coco was moist when transplanted into (rinsed until ppm of 20 and precharged with a very weak solution 150ppm at 5. and from what he said there was no root damage. He has given the plant a small watering every day around the center of the plants (where the roots were planted into) of 80ppm solution (a little superthrive, some dynagro kln, foliage pro, and protekt). His PH is @ 5.8 Water is 0-10ppm out of zero pitcher.

It has been 3 days since transplant. Day one there was a little droop, day 2 a little more, day 3 a little more. I guess he also changed his cfl's (1x23 6500k, 1x42 6500k) to a led (100x3 mars hydro at 18 inches above canopy). Temps and Humidity are ideal, good air flow.

Could this possibly be transplant shock? I told him to stop watering every day, could this be the solution. I can't get him to let me take any pics, so sorry about that. Please help!

This happened to me on a few of my seedlings couldnt work it out.. i put them outside for a few days stop watering them give roots a chance to recover it was transplant shock. How did u transplant them? They should bounce back give them time and minimal stress bring light up and less water

The leaves on his plant definitely look overwatered, but the lower ones are twisting and the twisting is moving up the plant. He can't put his outside where he lives. He says he did the same thing he has done before with 100% success rate: He gently flipped cup and broke off some dirt, then rinsed the roots, then dipped them in water very quickly a couple times until 90% of the dirt was off his roots (he said they were white and he didn't lose or rip any).
I don't go for the whole idea you can't overwater in coco, because i'm pretty sure he proved you can, lol. Now i'm just wondering why the twisting is happening.

OK, Been drying out for 2-3 Days now and his pot is feeling pretty light. I told him to wait another day. Is there going to be any problems with the top half of the coco being completely dry (light brown color)?
