Auto flowers in clone? that one pic of the leaf kinda looks like mg deficiency, usually caused by nut lock out. try flushing; if you tried that, then add a small amount of a mag supplement, cal/mag (botanicare) is usually what everyone uses, gives a dose of mag and cal, but usually nut lock out is what is happing cause you got nice new soil and stuff. Flush with allot of water if you have a 3 gallon pot I suggest using 6-9 gallons of clean phed water to flush and if you have a flushing agent use the recommended doses for that in the flush.
