My very first Grow

If you see any mistakes or you've suggestions/tips and tricks, please let me know! Thanks! ----------------------------------------------------------------------------------- Day 22: They grow like hell and look healthy (as far as I can tell). Day 23: On one plant I started to notice little balls. I'm a bit worried. I thought this kind of development only appears in flowering. Plants are still in a 18/6 cycle. Guess I'll open a question to be sure. Otherwise plants are looking great, maybe i water them tomorrow. Day 24: It's a dark day... had to kill 2 of the plants. Thanks to this community I was able to spot early signs of male plants and 2 plants clearly showed it. With one plant I'm not totally sure (left on the pic from day 24) so I'll wait a few more days. I knew that would happen since I used random seeds, but to kill them was hard and sad. Guess I can save fertilizer now... also starting to save money for feminized seeds (maybe also auto) Anyways, I watered them today with 1l for each plant. Day 25: Nothing to report. Day 26: As expected one more plant was clearly a male. I've removed him and now my last lady can have all the space she wants. I've noticed that the soil seems a bit dry, so I've watered her again with 1l + nutrients. I'm starting to plan my next grow. The plan so far is 3 auto-flowers from RQS but we'll see. Day 27: Nothing to report. Day 28: Last day for the week. Tomorrow I'll switch to 12/12 light schedule and send her into flower. Maybe a bit early, but with only one lady left I don't want to waste more time. So I can start my next adventure in about two month or so. I gave her another liter of water. Stats for the week: Temperature: 19.2°C - 25.8°C (66.6°F - 78.4°F) Humidity: 36% - 75% And she is 55cm (21.65 inch) tall
