I am pretty new to hydro. I have looked at several threads and am trying to decide what the problem is. Based on pics from other threads I am leaning towards ph issues (i am using a meter) or a nutrient deficiency but could use some help from more experienced people on what may be going on.

System- ebb and flow.

Flooding - every 12 hrs.

Medium- trying Sure to Grow inserts. They retain water pretty well.

Res temp 68-71

PH - 6.0

PPM - around 550

Light - 1000w about 4.5 feet above plants

strain - Arjans haze

Age - 7 weeks

Attaching pics. Thanks for any help!

This is my first time with ebb and flow. I am perplexed how it could be nutrient burn because I have been adding such small amounts to a 45 gallon res. I was thinking I was way low in nutes by this time in the grow but my ppm says its around 550 at the highest amount. I am using bontanicare pure blend and not even adding 1/4 of what the bottle suggests. i don't understand but thanks for the help.

BlueGrassOne, I am not sure what you are saying. Are asking why add nutrients at all? Do you grow hydro without adding Nutes?
