Should i be able to spot sex at 2nd set of true leaves? i used a magnifying glass a, 1 has 2 tiny hairs and the other looks like 2 balls... just wondering if that was chance, or if you can tell at only 3 weeks old...
No way. You can't tell sex until it starts to flower. Once you switch to 12/12, give it a few days and look then.
It's all good. You should take pics all the way through. Start a journal so everyone can help you along. It's the single best thing you can do to ensure that in a couple of months you're smoking some dank homemade weed.
you are correct... cant believe i forgot about those, and missed em when i looked at that pic. thanks!
When the plant starts alternate nodes (or close to it) you can determine sex. I only have 2 grows and I always know the sex before switching to 12/12. This is with indica dominate strains. Sativa dom could be different as I haven't tried those. hope this helps
not true .. after week 6 cannabis will show preflowers..and You can verify sex with those. start by looking on the 6th set of lateral branching/leaf nodes, on the trunk.. to the OP .. why don't you read the sickie about finding sex? http://forum.grasscity.com/absolute-beginners/454814-sexing.html wharf.
