***NEED SOME ADVICE*** curling leaves and slight twisting

I need some help fellas...I picked up some clones and transplanted them into their new home 5 days ago. Prior to transplanting them, they were healthy and full of life. Please take a look at the pictures and give me any insight what may be the problem. Here is a brief background:

Strain: Lemon Larry
Media: Growstones
Feed style: twice a day drip feed @ 2mins
Nutrient Mix: RO water with just cal mag 5ml/gal (flushing them to prepare for veg cycle)
humidity/temp: 55%/78 degrees F
ph:5.8-6
ppm: 336
t5 lighting spaced enough to not feel any heat ontop of the plants
air is circulating throughout the room
the grow area has concrete floors where i just applied some concrete sealer (polyurethane based). ( let it dry for 3 days before placing them in there)

they are starting to curl up and some are twisting. i found some sites where the tips are burning. Im relatively new to growing but ive done this before without any problems. Am i doing something wrong with just using RO and cal mag combo? They look like they are going through nute burn and/or ph lock. but all those parameters are within acceptable range. I checked other threads and concluded the following culprits: too much nutes, too hot and too dry. Am I missing anything?

I foliar sprayed them with some nitrozime thinking that it may need some more moisture.

any input would be much appreciated. thank you.

I don't see much twisting that's more of upward canoeing of the leaves
Why they do it I don't know man I would guess the nutes are a little to hot
or the wrong combo of nutes. Have you ever tried using just the regular
veg nutes like Sensi Grow ?

That's the thing the only nutes in the reservoir is cal mag...that's why I don't know what is going on

maybe your adding to much cal mag?

lord have mercy. upward curling, or taco-ing, of leaves is from too much heat and or moisture. stop the foliar feeding and raise the lights or find another way to lower temps.

The temp and humidity are on check...76-78 and 56%, respectively. I'm just scratching me head on this one fellas.

I raised the lights and turned off a few banks from my t5. Is there such a thing as too much light?

anyone else want to take a shot?

had that problem with a few plants closest to the fan
