a little tip for you is to- when roots start to show at the bottom of your pot have a spare bucket and have your feed and nuits in the spare bucket, sit your plant in it for about 5 mins, then remove, the plant will have taken what she needs, repeat the same with the rest, topping up the bucket each time it starts to get empty, you only need about 3 or 4 inches of water & nuit mix in your spare bucket but the plant will always just take what they need, ie a good drink, when the pot is nice and dry and feels light to lift just repeat ok, thats a much better way than to stand and flood it and not know what you have gave it, you can up the standing in the bucket time as she gets bigger to around 7/8 mins, best of luck to you fella.
This will save the guess work as the plant will only draw up from the bucket what she needs, just like any animal etc they walk away when they are full, so lift out your girl after 5 mins she will have taken what she needed, saves you pouring away into a pot and not knowing how much you have gave her, trust me on this one.
