First grow!

Hey there, so growth rate is determine only by VPD which is the relationship between humidity and temperature. in your case you need a humidity of around 60% + . You can get a mister (underrated piece of kit !) or just spray it with water up to six times a day to maintain the humidity. Hope this helps ! 🚀

Dont worry it's a she!! Those "balls" with hairs coming out are called calyx and they are the female part of the plant. There would be balls on a stem if it we're a male or herm 👌👌

Looks like a classic calcium magnesium deficiency probably caused by lockout? I notice you're not feeding any calmag, it is strongly recommended especially when using led lights for some reason. Same thing happened to me with the mars ts1000 too! Check out my bigdevil on quarantine grow. You will need to flush heavily and add calmag to your feed she should get a little better, but those crispy leaves won't. 🌱👍
