when should your leaves start yellowing??

i've got a few plants about 6wks into flower (8-9 wk strain). two of them are starting to yellow and drop fan leaves; i know this is normal towards the end of flowering, but is three weeks away from harvest too soon for this to be happening?? if so, should i give them a light dose of nitrogen?? please help

no, it's not too soon . this is absolutely normal. don't worry. They don't need too much nitrogen at this stage. wait two or three weeks more and enjoy put some pics if you want...

no worries... most of my girls started showing yellowing of the fan leaves in the first week of flowering
