hi guys!
i bought some snow white seeds and I have a small growbox,so idecided to start flowering at 3,maybe 4. week. it isnt too early? I dont want to get a BIG yield,just want to get some results

so - if Ill start flowering at this time - what about nutrients,when should I start to add? if the veg time ll be about 3 weeks,isnt it too early to add some Npk and another nutrients? I wont hurt my plant?
and quest. about sex[when it'll show a gender approximately ? ]
