watermelon zkittlez closet grow sf1000

--day 98 for watermelon zkitlez ,and first time ever when a plant did something strange and aborted in mid-late flower, Really hard to find my words to say this as nicely as possible to not think i am a hater ,yesterday all seemed fine until i looked around one of the watermelon zkitlez,she had branches dropping down,wilting having curling in leafs and all seemed healthy at first aspect,so i took some calixex of and each of them which opened had micro seeds ,which makes me belive something happened and the plant suddently started dieing off ,yield wise this is disgraceful for me and a total waste of my time ,only good thing coming out of her is some fudgy brownies but that's it,i talked to barney about this and the DOS-SI-DOS which just doesnt wanna flower properly even after 76 days of life ,which is insane! but that remains to be written in her own diary. the other one is doing fine but the bud structure is just wacky fluffy and all over the place ,my VPD is dialed in ! i do not want to go into details as it only makes me frustrated more about this and i am thinking of chopping all the barneys down and moving on ,because was a total waste of my time ,can't blame the nutrients,can't blame the lights,can't blame me ,because all my other plants are doing just fine ,go check them out !
