Hay man.
What i would do if i was you is stick to a feeding regiment and cut whatever you think you should give them in halve. I don't think they are missing anything, It looks more like something burned the shit out of them. They will smoke fin in the end. The MJ seems to do bettor when its not in the richest soil or in your case watter. Some things are good but it just looks like they have had enough stress from changes and way to much of a good thing.
I would also leave the door on that box open as much as possible. Let some good air in just in case the fans don't do the trick and make damn shur the temp don't get to high.
I have always had a green thumb. Don't know why but that is what my instincts would tell me to do for them girls.
Hydroponics is a pain in the ass. You can grow some fantastic shit but at the same time shit can go fantastically bad, FAST.
Looks awesome for a first timer jumping right into hydroponics. I did read this was your first right??? O well
Peace.
Tap water? No wonder. Even without chlorine the minerals and such in tap water will throw your pH WAY OFF in such a small container. Well, you'll know for next time...
I've been using a converted lucas formula, halfed for the Autos... I'm thinking that the issue was heat, or tap water related, as I did have to use some tap water a few times, I left it out over night to evaporate the chlorine. I also took out the 23watt, and am now just using the 2-68 watts, new growth is green and healthy.
