A few questions and pics

These are my plants at about 7 weeks. I just switched my lights to 12/12. I always point a fan at the plants when the closet is open, should i continue this through the Vegitating stage? I heard you can easily spread male pollen with a fan... Otherwise, how do the plants look? I am concerned about my biggest plant, the leaves are droopy (see last pic). Any idea what this is from?

Dude this is a hard thread for me to read, it soooooo wide. lol
Is that foil I see, maybe causing hotspots?
Keep ventilating, you have to ventilate unless you use a closed system
with co2 enrichment, which you are not. The ventialtion is a multi reason technique,
meaning besides helping the stems get strong, the plant uses up the available co2 in the air,
and the ventilation allows new co2 to come in the room for the plant to grow healthy.
Peace

those look great for 7 wks the droopy one might b a little overwaterd

Your plants look nice dude, keep the fan on em and once you see balls then kill it. dont be worried about one droopy leaf, the plant still looks healthy as shit. all you gotta do is wait till you can tell what sex they are. peaceee

Dude, thank you so much for editing the post. (old eyes here)
They do look good. At about 1 to 2 weeks into flowering they'll show there sex. Remove males immediately.
Have fun with your grow!

As far as the fan goes, keep it!! You need the air to be circulated in the grow room so there is no stale air. You will be fine, just check frequently and you will soon be able to tell the difference between the females and males. Males shouldn't spread pollen until the sacks are opened.

Your plants look very healthy. The color is perfect on your plants. Maybe you would want to transplant them soon because they will double and maybe triple in flowering. Those pots look a little small for how big they are. Good luck with harvesting!!
