The symptoms seen are probably carryover of the cloning process. some have healthier rooted clones than others.
If it was kept in a high humiditty / low vpd environment until you tent, it may just be adapting. It'll be a bit more sensitive to dry atmosphere or higher vpd.
What's on that leaf? Can't even diagnose that, lol. If from a foliar spray, definitely stop that. Also, a blurry white spot on same leaf on the leaf blade pointing left in picture looks like a smeared WPM colony. hopefully it is just a water stain of some sort.
clones can be risky... when produced en masse, some portion inevitably have mold and such when money is inovled. Better to ask forgivness than permission type behaviour... i.e. sociopathic.
