new pics more ?'s

Hello all,
plants look happier and healthier.
i have some ?'s but think that some info is needed first.
the seeds(mixture called the doctor) were purchased through a "suppossed" well known dutch source and were provided to me by the medicinal user who suffers from chronic neuropathy pain, and isn't capable of the daily maintenance for the plants i.e i'm the caregiver.
after lots of research he picked the seeds, white family and skunk mixture, purchased them "feminized" to eliminate male infestation and increase cloning capability.
is it normal for the difference in the plants to be so noticable? look at the front one in pics. the leaves are much thicker and the root system is shorter and fatter.
temp of box is maint at upper 70's 24/7
lights 18/6 for veg
after adding frozen gallon jugs"ghetto cooler" to keep water temp in high 60's to low 70's
humidity is in the 30's
ph is avg 5.7
keeping ppm at 700 currently
using 2/1 bc boost/grow per gallon
adding approx 1/2 gallon of fresh water every other day
think i might be able to start cloning next week?
do the plants look healthy to all y'all?
any suggestions/tips, lets face it, any info would be greatly appreciated

I dont know much but DAMN those look sweet :D "The Doctor" Its a Greenhouse seed strain, need I say more? It has close to 20% THC level .. I too wanted to purchase those fem seeds, but they were sold out :mad: I know you took em ;) Good luck on your grow Ill be watching for sure.

They do look lovely indeed. Don't know anything about cloning tho...Good luck.

i only know what i've read on this site about cloning. the gr has a shelf up top for specifically that purpose and i thought i might try to do some cloning to shorten the process

I personaly would give them some more heigth before cloning. I wait till I see sex, till I clone, but I never purchased feminized seeds either.
They look very nice. Probably a silly suggestion, but 4-5 years ago, I figured out I could elevate my box, then I cut the floor out so I could *sink my medium thru the floor*. My hydro runs, were WAY cooler!! I think even the tubs I used ProMix in benifited from the cooler medium temps. Not all set ups allow for that kind of radical effect tho.
