First time grow

At that stage better water / feed / water / feed and repeat. Don't water every days it's the best way to create an over watering issue and I also recommend you to give half the dise to your baby and if she accept it well this increase the nutrient input. To water properly, you need to lift the pot when the soil is dry ( remember the weight ) and do the same after you watered and you will only need to water when the pot will recover the light weight !

I would bet for the previous overwatering issue it cause such issue, you can search for over wating issue and how the leaf looks like, these nice gals hate too mutch water it's very important as someone said above you water but stop unless the soil is dry (touch the soil to check if it's dry) if it is it's time to water but not a lot again :) anyway that's how I see this issue but I could be wrong. Good luck the rest looks perfect nice jobs for a first grow, my first grow was so shitty I didn't even show it to anyone and got 15gr out of it lol, but how it is going you'll get get some nice and huge buds ;)
