Leaves not looking good

I'm just not sure if my young leaves are having multiple problems, looks like it maybe? I wonder if these cheap Hanna checkers for ppm and ph are not doing the job. Plants are under a 400w cmh light.

I have used:
GH Flora Micro
GH FloraNova Grow
Superthrive
DynaGro Protekt
Real 35% h2o2 diluted to 3%

I topped the girls a few days ago and took off the bad leaves and changed the res and problem came right back in a few days.
Any ideas would be appreciated.

IMO, it's calcium deficiency.

I am using half RO Water and half well water. Wouldn't the well water have calcium in it?

Any more opinions or Tips

look up Zinc deficiency and see if that looks like what you have. That would be my guess.

IMHO, it looks like Ca and Mg issues. Looks a bit pale too.

I c some burn
do u use distilled water?!
U should water with fresh water no nut only correct ppm

Thanks buddy, my wife picked up some cal/mag in town today. I think when my son gets home I'm gonna dump the water and just go to some good ph'd water w/some superthrive and some cal/mag and give them a little break.
