Topping During Flowering Cycle

Lets say you have 6 white widows under a 400 watt hps. Lets say you vegged them for 4 weeks. What if they were on their first week of flower, and you wanted to top them? Would there be any negative effects?

damn can somebody answer this guy cause i need to knw this also

you need to top em in veg and its advisable to give them a few days to recover before switching em over to 12/12

dont cut anything in flowering u will be fucking up your numbers, 2oz, down to 1oz. when you cut in flowering they dont grow back like in veg
