i have been using the mj nutes i bought a long while back, since i have random bag seed tho, im wondering how soon i should do a flush, since i dont know when final harvest date is its hard to time out 2 weeks prior. im in the later part of week 6 , il attach a picture hopefully some of you could help me out. if it helps any smell is fruity, fairly lemony. i also have a few pictures thru the stages of development in my grow log. thanks for any help
