Please help flowering plant!!

2 of my plants look bad they are 3 week in to flower and only 2 that look like this is northern lights
I'm thinking to much nutes so I only watered this time with plain 5.9ph water. maybe do that few times
Temps are lights on 75-79 lights off 66 to 68
humidity is 32 to 39%
botnicare nute line
1000watt hps

when I use the botanicare bottled I cut the directions in half in pure pro mix and water water water feed as needed, water water water water harvest when bucket is light. the experience is really tops. I'm considering dumping my beloved Organicare dry ferts for the bottled version. I hate the poop dust, but it really is a fine producer. you have worked with plain water without ph'ing?

looks like it might be too much N
to me
