Are they all the same strain from one batch of seeds? if so-- could be genetic-- if not.....
check the nutes and pH AND your meters!!!!
we have a Sativa with a LOT of thai in it thatthe while thing has "corkscrewed" leaves all thru the grow-- no matter what we changed... don't know if it is because of root damage or the fact we had to supercrop it to keep it under 5 feet--- but it's NOT happy.
As long as it is HEALTHY- and you are sure your meters are calibrated & the ph and ec are "right on" ... I'd just watch and see....???
No need for revenge, just sit back and wait.
Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
