Should i keep these or start over?

i paid 13$ for 9 clones over a month ago and theyve only grown about 2 inches. i got 5 atomic haze and 4 pure skunk #1. ive been fighting to keep the ph at around 6.3-6.7 and it seems the clones arent responding. theyre growing at a very slow pace. theyre in ocean forrest and i have fed them 3 doses of superthrive along with 2 doses of grow big. heres the pics. tuesday im going to the med club and buying all new clones if these clones wont grow. it costs about $120 for 9 of em. but shit, i had no idea that healthy rooted clones from the club would stunt on me. what the fuck went wrong?

Yeah but clones don't grow instantly. It takes a lot longer to take root than starting seeds do. Most people use clones just to continue a strain that they really like.
I have clones I took from topping mine about 4 weeks ago or more and the seeds i started growing 2 weeds ago are started to grow bigger.

What kind of water are you using. It could just be an impurity if your using tap. I would flush and use distilled if thats an option for you. If the clones are from the club there usually already rooted and should be ready to go. Seeds will take about a month longer to get started if your gettin rooted clones from the club. If you dont mind spending the $120 I personally would do that and prolly save one or two of the best looking that you have and try and fix them and learn from those.

i use a dome

flushed them all sunday about five days ago with 6.0 purified water. all of my plants are at about 6.5 ph. i fed them yesterday a full dose of superthrive and bigbloom and a few seem to be growing a bit. but tomorrow im picking up 9 more so ill have 18 plants vegging under a 400 watt. ill probly throw some t5's i got under my bed on 'em to get some more light in there.
heres what they look like.
