First time grow log

Well I was trimming Ruths bush, which was very thick btw. I looked down and saw Jael. She's a small premi and I thought what the hell, I'll see how it goes just growing in woolrock. So her is Jael and her big sister. ;)
OK I got a question, here is my routine. I know over watering is always a big mistake noobs make so I want to make sure. I feed the mother plants 150ml of mixed Iguana juice grow on Wednesday and Saturday, then on Sundays I water them down good. They are in 10 gallon grow bags. Now the premis I give them 50ml same days.
