Sexing plants?

[sgt. schultz]

Hi to all my friends from RM's site. Starting 3rd run from seed. Previous 2 only started 10 and had 6 females. Was super hard to keep temps low enough in hot climate here so I am trying 1 bigger run before heat of summer. Now I have 41 seedlings in 20 oz styros for 2 weeks. I have 10 WW (out of 10 germed from AMS hooray for them), 9 SHP from RM (out of 10, yay) 2 SD and 20 unknown from very respected farmer known by most here I'm sure. How old do they have to be to sex them? Do I have to transplant them all or can I leave them in styros til I can sex them. Three sets of leaves right now. Should I start feeding now? Thanks for any help, browsed every page in this thread.

Lots of variables of course but I start in styro cups, 16 oz. After 4-6 weeks I transplant into 1 gal bags and 1-2 weeks later am ready to flower. My earliest girls were showing sex at about 5 weeks. Some not until 7 weeks. If your growing in soil and the plants look healthy then you probably dont need to feed. I dont grow in soil much so I dont know for sure but the variables there are what type of soil and whats in it to start with. I usually let my plants tell me when they need something. keep an eye on the bottom leaves and they will let you know when they are hungry.

when you say bottom leaves are you talkin about the ones that look like clovers?
