please give me feedback... First time adventure

This is my first grow.. i have two female clones i have put into flower and its been about two weeks now.. these looked the same at the beginning.. (left) cyclone (right) gummy bear. I have them in smart pots, using fox farm ocean mix, 1/4 dose of nutes, 1000 watt hps, ghetto air ventalation, temps are about 80 give or take, huminity i cant get to stay around 50%, any info is good info.. my gummy bear is upset... cyclone thinks this is the coolest thing its ever seen... i dont know what to think.. after reading up i tested run off... it red 7.0 whats that mean..?
Anyway... Please help a ghetto stuggleing modern day farmer...
Thanks a bunch!

the plant on the right appears to have nute burn and the one on the left seems to have a bit of a deficiency, take sum pics without ur HPS on it kinda destroys all quality of a shot
different strains and plants have a different preference for taking up nutes
your gummy bear seems to prefer less, while ur cyclone is edging for more

ok il get some more pics up.... i decided to up cyclone.. while givin the gummy nute free water for a couple... we'll see.
