How are my girls lookin?

First week of flowering these 8 plants...4 of which are clones. 2 white widows and 2 hash plants. The other for plants that are big are seeds I had stored away and they all turned female! just wondering if they are looking normal to anyone else. tell my what you think guys!

***I was also wondering on how much to feed/water them they are all in 3 gallon pots. I currently give them water/nutes @ a 1 liter serving, and I give them that every other day or so. Can I give them more without over watering them?

I think they could use less N.those leafs are really dark and nute burn starts on the bottom and works its way up .Other than that good job !!!! are you using kelp if not they love that, Happy growing!!
