just so all yall know,
Safers does have a shelf life, and, if you mix it too strong,
it can burn your leaves, or cause mutations, and effects ph with too much run-off.
if your safers is new than you prolly just mixed it too strong.
spray with plain water once a day for two or three days to get rid of any excess residue so that it doesnt get any worse! also, you may want to raise your light when you spray, water droplets can act as a magnifying glass and cause little yellow burn spots on leaves. and they usually occure on the edges...
just a thought,
may or may not pertain to your particular situation though!
good luck
