Thanks mate appreciate the reply... It could be heat stress you could be right I also dealt with catterpilas not long ago still find the odd little cunt hiding but nothing to major I'm running 600w boost hps lightit doesn’t bleach everytime, it could just be stress from the light. That happens with my quantum board. It confused me quite a bit because I always thought they would bleach if it’s too much, but that’s not the case. good luck. At least they look frosty as hell.
