What is pot size for 3 week old ? Hi i have a 3 week old Amnesia haze i sniped her at a week and a half ,just once at tip . She is 10inch away from a 250w HP's with a nice breeze from fan temps 78-84. In all purpose soil. I had her in 2 litre pot and noticed she has slowed growth ,when i took out of pot there was a lot of root growth . I have since put her into 3 litre pot last night and gave her quarter of strengh of baby bio . This morning her biggest fan leaves were a bit yellowish at tips ,does it need a bigger pot ? forget the nutes the now ? Or just watch her for the now . Also what will happen when she is flowering is she going to grow more roots !
