DWC Leaf Droop

[Arobbz]

Hi, so I'm a first time grower using Hydro (DWC)
I got my seedings on friday and transfered them in to my DWC system. Everything was going fine till sunday morning when I noticed 3 of my Delatos plants have started to droop. But the Sorbet is doing great!! Somebody told me it looks like I have been overfeeding and so I lowered the water level to about 1inch under the net pot the roots in the pot are still getting wet. I checked today and some of the leafs have started to crisp and get brown looking burns on the sides. I'm getting worried that I'm killing my babys and would love some advice to save them lol. Any help would be appreciated thanks dudes.

3 x Delatos
1 x Sorbet
600w HPS
Room temp 25°
Water temp 22°(trying to lower)
Ph 5.7
EC 1.0

How do the roots look, very white or dark

At that age the water should be about 2" below the bottom of the net pot

Lots of bubbles??

What nutes and strength, not EC, % of manuf strength

How often do you change water

Any enzyme cleaner like Hydroguard or z7


Not a fan of tin foil in yer rezz lid either, can creat hot spots I believe

Roots look tanned but not fully brown they come like that and was told it is root stain.
Using Katana Roots 5ml/L and Shogun start 4ml/L
Today I have put in "Silver Bullet Roots" and gave the roots a little wash down. And changed the water.
