Sorry for the lame question but i have spent hours and am just more confused than ever. I have a friend with a 14 gal rubbermaid (1) with 5 plants. Setup one week ago and left unattended untill now......(unexpected clones one day before trip!!!) Using GH 3-2-1 mixed up 10 gal worth in 12 gal of water (not ro) used tap 15 years ago w/ no probs!...but anyway the light is 430w agrolux hps heres problems:

Leaves(lower) turning Completely yellow (not just tips) and am confused as to whether this is a N deficiency or a burn (2 totally different remedies!)

Ph is 6.2 (or lower since this is the lowest my reader goes!) problem?

have bubble wall and 2 airstones and roots growing out of pots already but new to this (i thought i was making it up as i went, then found this site.....duhhhh) i'll try to post some pics

Thanks (cant get pics to upload but leaves are totally yellow on bottom of some)
