questions about growing!!!

ok so im on my 2nd grow with a new soil and clones.
im using an aerogarden 7 for toplight and about 12 CFL lights for 360 penetration of about lumens.
the soil is at about 7.0-7.2
im switching off from a solution of foxfarm bigbloom and and botanicare sweet thats at 6.7-6.8
and a solution of tap water leveled out to 6.5-7.0.
my main question is how can I fix drooping yellowing leaves with brown spots?
ill try and get pics up soon.any help is appreciated thanks!!!

ok so i checked and the total amounts of lumes is 14,400

from clones, about 1 week into it,
yes tap water is from the city,but its balanced out to 6.8- 7.0

i have 2 clones
1 bubblegum and 1 skywalker og
the bubblegum looks decent and is growing with some browning and the skywalker is yellowing up

I would probably stop feeding them nutes for a week. I would also probably get better water, and/or try letting the water from your tap sit open in a bottle for 24 - 48 hours. This will get the chlorine and flouroides to evaporate... or so I have been told. I use reverse osmosis, and that tends to keep things pretty nice for me.

i also forgot to mention i am starting to get filtered water thats about ph 8.0 and im adjusting it down to 6.8-7.0 during this week of no nutes. should i stabelize it to a lower ph, lets say around 6.0-6.5??

and here are some pics of the bubblegum

and the skywalker

any other advice that might save these ladies?!?!?! im kinda desperate and there getting lighter in color by the day with increasing brown spots!!!!!!
or should i just get new clones and say fuck it??!?!
