5k invested in grow and now i'm in some shit NEED HELP

My fellow GCers I have a dilemma which needs urgent attention from a knowledgeable indoor hydroponicist. I have over 5k invested in my perpetual bubble bucket indoor grow and I have a serious problem with my clones. I have a NL feminized mother growen in soil which I took several cuttings from, I put 5 cuttings in my bubble cloner and 5 more into grodan rockwool cubes. They showed bumps in about 3 days and I transplanted 3 rockwool clones into 1 gallon veg bubble buckets and bought 6 clones from the clinic also in rockwool and put those into the other 1 gal buckets. I have a 9 bucket veg chamber. My problem here is that the clones from the clinic have already showed roots outside the netpot and the clones from the mother (over 2 weeks old now) are wayy wayy behind, the roots haven't even popped outta the rockwool cubes.

I don't know if i'm doing something wrong here with the clones I took (which i'm pretty sure I did correctly) or if I'm just being impatient with them. Either way, I could use the help of an experienced hydro grower either on AIM or through email to help me through. I could arrange compensation if the person is able to help me well enough.

I am vegging under T5 flouros, flowering under two 600watt HPS's, using botanicare CNS nutrients, supplementing with superthrive, and misting once maybe twice per day with PH balanced superthrive+CNS foliar mix. The PH on all buckets is kept around 5.3-5.8 with PPM being 550-600. The tap water here starts at like 300 so I add nutes up to that PPM.

One more thing, while I was taking my first batch of clones I noticed white pistils coming from the nodes on the clones, did I switch them into flowering on accident (im running 18/6 obviously) or did a light leak mess them up possibly? Could my poor rooting speeds be a result of early flowering? I'm hoping this isnt the case or the whole batch goes into the trash...

HELP!
