Did i take the right steps? Will it live? :)

So i have embarked on my first grow. Me being gung-ho about this type of thing i went all out and bought (at a great deal i might add) a GH Rainforest system. http://www.plantlightinghydroponics.com/rainforest%C2%AE-aeroponic-systems-c-33_452.html Not from this site but this unit. I bought my plants as clone(just two atm) that were in a soil wick type grow. Well i washed the roots as best i could and planted in my full hydro/aeroponic system. Well stunted growth ensued, as i would have guessed, and it seems to have taken a while for anything to happen. Some of the larger leaves turned yellow and then died altogether. One plant is and was much worse than the other, which i believed to be caused by my net pot liner, i believed cut off nutes or perhaps drainage; so i repotted that plant.
then later I diagnosed(perhaps mis) the problem as a potassium deficiency. as most seem to do i added more nutes and nothing changed. further research led me to believe that the water i used was no good(i thought perhaps too high sodium, or other) so changed with distilled water and fresh nutes. after about a week the plants seem to recover, although one still worse than the other. Girlfriend pruned the bad plants dead leaves while i was away for a few days.

Now the plants both show new growth but still some discoloration... at last, however, my testing supplies have arrived. Great success :)
First thing i did was check PH; 5.2. Not great, not horribly horrible. Really not sure how bad this is. I added 2 gal of 7.2 distilled water last night to try to bring it up a bit. Getting some PH up/down today.

Next was the PPM. PPM settled at 1080 on a Hanna unit. Note that i am still in Veg so this, i believe, is very very high. The plants did not seem to show typical signs of nute burn, but then again that could be it. This also prompted me to add 2 gal of 0ppm distilled water to bring it down to about, guessing, 800-900. If this is the case is this ppm livable for another week or so before flushing fluids?

I will add that up until a few days ago i had no root growth outside the net pots on either plant(ok maybe a half inch on the better of the two) then 6 days or so after last check i have a few long roots beginning to dip into the solution.


ANY comments, questions, suggestions, etc are GREATLY appriciated and i really do mean that :)

I will also update this afternoon with new PPM and PH readings.

Pics below are of the plants as of last night. one of each plant.

Thanks again

PPM was 930 today
ph was 6.2

so adding water helped with the ppm for sure, should i add more and be prepared to use some ph down?

tnx

Here this might work, ease off the nutes, and just use something light like superthrive. Plain water works just great. The ph lvl is just right. Your leaves are yellowing, have the piter-pat pattern. These are signs of zinc, iron and magneism deficiency's.

Do you suppose that the reason i have these deficiencies is because of nute lockup? ph was too acidic and roots were unable to absorb the nutes (back when ph was low 5s)? im using GH 3 part nutes btw, all calced to the 12 gal i am using.

also i am using super thrive, just a touch as a boost as per directions.

thanks for your advice btw, i will look further into these before i act.
