Bagseed and Master Kush DWC

ok im in a pickle... ok i have a bagseed very pretty bout 2 1/2 - 3 weeksold. but right beside it i have a 6 day old masterkush... the bagseed has been trimmed a lil and topped im goin to hold off flowering i guess for a lil while cause im really trying to get MK clones!!... but i was going to order some more fem seeds in bout a month so i can start somewhere fresh. any good newbie strains with massive yeilds?

although i have been trying to take clones of the bagseed none have survived yet all die within hours... so in bout s weeks i will make a dyi auto cloner... shoul i use misters? or a DWC type cloner.

my previous attempts of cloning i used clonex and a 7" cutting clipped fan leaves and put in rockwool in a dome.... currently trying just water and a cup lol... im a newb but am trying to aspire to gro bout 8 clones a month...

im currently ussing a DWC 5 plant 10 gal res veg box i mae with 3 42 watt 2700lk and 3 48 watt 6500k...

any advice or help on my grow or cloning. anything please help. i might be making it harder than it looks in my head...

here are some pics of the gro so far.. i was lookin for preflowers.

you don't need the dome..

do you soak the RW cubes in ph5.5 water?? do you add any nutes?

how are they dieing?? lower leaves yellowing?? tips turning brown and crispy?
floping over??

new update

hey man thats wut i do is clone in just a cup of water with a drop of super thrive from wallmart. works for me keep it up looks good and youll get the clones soon

so the bagseed is 3 weeks old i beleive today looks like a sativa stain.... but the mk is bout 9 days old maybe 10.the mk is straight leaves perfect color but the bagseed has roopy leaves im thinking it might be a pakistani strain or something... idk any avice ph is at 5.9 and im at full nutes now
