FUCK YEA U CAN!!! DON'T KILL EM U'LL BE SORRY. instead get some duchmasters Reverse n spray em like it says, follow bottle directions including follow up spaying. also remove any sacks by hand n inspect every other day for more sacks that may have busted out.
did u hit em with some kind of a nute heavy in P? too much P will cause this esp. when given early in flower, some flowering additives like
phosphoload can cause this too
top booster as well.
not to mention if u went in ur room during light's out/night or even a light leak, spray em wit Reverse use da saturator that they recommend n spray with lights on like bottle says (30 min b4 lights out is good). it works!!!! don't waist time get on it asap, wish u luck n hope this helps. Peace
