I changed out my reservoir 48 hours ago due to the leaves curling under and the leaves turning dark green. I lowered the PPM from 700 to now 320 based off of what I had read about possible nitrogen toxicity. I am new to growing so any advice would greatly help.
They are looking good. Your feeding and checking the correct things.
Here’s my 2 cents:
Add some beneficial microbes to your root zone.
Drop you water temp below 70 degrees by freezing a 2 liter bottle overnight and place in your water been a few hours before watering. Cold water can hold more Oxygen.
these are good numbers for what I can see without knowing more…one of the nice things about hydro is most times a good flush can get you back on track to goodness…
