I got a couple plants in the grow room who are all a couple weeks apart. I have 2 3 week ish old plants who were super small and stressed and I put them in and fishtank set up at three weeks. At that time I planted a few new plants who are doing great. The new plants are about 3 weeks old now. This means my old plants are about 6 weeks and Im worried one might be male. They are still smaller and just starting o grow quick so I wanted to keep them going. What do you guys reccomend? if a plant is 6 weeks but only a foot tall and only growing well and good for 3 weeks can it be sexing yet? please help
