First Grow NL Auto

First week of veg nutrients. Complete noob and first grow but did research heavily, started nutes at 100% and within 24hrs she was showing nute burn. Flush and restarted at 50% and she showed signs of stress and nitrogen deficiency. Veins on leaves were rich green and leaves were showing yellowing similar to a halo on leaves. Finally, corrected nutes to 75% and she seems to be thriving with no issues. Did run into a fear of root rot due to temps, thankfully was discoloration from hydroton that I didn’t rinse well enough, ph was too high and water was warm from a few days of growing. Last, utilizing a 5 gal. dwc with 4 gal. of liquid, lowered it to 3 gal. to allow air spacing for roots, water level was touching bottom of net pot.
