bought a timer couple days back, 4 n a half weeks in to flowering , n went up today n noticed the light had stayed on, i realise now that i set the light up wrong so means the 250 hps has been on 2days max continually, so wots the chance of them hermying, been told from guy at growshop to leave the light off for a day so they revert back to flower quicker, and will this have an effect on my overall yield or can i just chop off male preflowers and the rest wil grow as normal. also how many days has this roughly set me back or are we speaking a matter of weeks ?
