first indoor and mini dwc grow

Hi this is my first indoor grow and also my first attempt at dwc growing. Im growing 3 bagseeds in a very small cab. I have 3 cfl's 1-26w 1-23-w and 1-19w all different spectrums. In my dwc setup im currently using a large Flanagans cup as my res wit two air pumps running lots of oxygen to roots. Im using General hydroponics flora series and rapid start for nuts i have no ph tester or ppm meter i know i really should givin the small size of my res .... please any advise would be helpful

Im sorry it took so long to get pics up but honestly i just figured out how to do it lol the set up has kind of changed tho. My 19w cfl blew on me so now i have added 2 14w cfl's in its place and today i built another larger container for my dwc setup and just tested my ph today wit cheap color indicator and found out my ph is round 6.8 high i know but everything looks perfect as of now. Im also only growing the dwc inside to give it more space to grow i had a real bad burn early in dwc and lost a couple of leaves but it is strong now what do u think any advise is helpfull thanks
