Having issues I can't figure out.

Hi... New here and I'm having an issue in my DWC. I am at 5.8 pH and was running my ec at 2.5 and just flipped them 2 days ago and changed the nute mix as well. The leaves started looking like the pic... I freaked a bit and reset the nutes at 1/4 strength and my ec is now .9. is this nute burn and if not what could it be... My buckets run around 74 degrees so I am using hydro guard as well. Any help would be greatly appreciated... Thank you!!!

2.5 EC is way too high.

Were they already looking like that before you flipped or was it after you changed the nutrient mix?

No need to change the mix until a couple weeks after flip BTW as they are stretching and could use the veg mix.

EC too high. I would run ph water for 24 hrs then feed at 1 ec. Let them recover!
Res temp could be lower.
