Over watered or under watered??

Hey so I've grown outside a few seasons now but have just tried my first indoor grow under a hps 600w lamp and the girls seems to be chewing through the water. I don't want to over water or under water but by the looks of the photo do they look like they need more water or have too much??

Too much nutrients? Should I flush with water ? I'm feeding with nutrients every water maybe I should split that up with normal water in between?

Take pic with natural light please.

Also we need more info. What medium are you using? Nutes? Lights? Birthday? Social security number, address?

You know all the pertinent info lol.

Or maybe just the 1st 3 to start

Hahaha sorry. Growing in soil, feeding green dream bloom 1 tsp (5ml) per litre. Was advised to feed this to them every feed but maybe its too much. Using a hps 600w on 12/12. Halfway into 2nd week flower now!

You don't actually need that other info though aye?

The last couple of days,I have noticed this weird receding tips of the leaves almost forming round edges?? Could this be a form of over/under watering or light stress?? Also some of the leaves at the top of the plant feel out of life and wilted.
I am running a hps 600w lamp with a 12/12 schedule.
Dehumidifier keeping the humidity between 40-50% and the temp around the 25-28°C mark.
