Yeah I just saw the other older thread you posted a month ago having the same kind of problems. In that thread az2000 gave you the real dirt, but there was also a lot of guessing going on in that thread.
I'd pick up some florakleen and flush the snot out of them with about 100% or more runoff. Wet them with florakleen solution and let it soak for 5-10 min then flush it out with loads more water until you get runoff below 2ec max.
Next watering give it a light feeding around 1.2ec/600ppm or so at a ph of 6.5
You will probably need to top dress a little dolomite lime and agricultural gypsum on the surface of the pots and gently till it in afterward to recharge the soil. Do that after you flush, and dont go overboard man... Like a tsp of each, it shouldnt need much. Couldnt hurt to add some humic acid and sea weed extract also. Any time you flush the soil like that you're messing up the balance of all the things that make it work well. But being in week 2 only you have time to recover this I think. But you've gotta get on it.
