RQS Royal AK Auto

Hi all! Starting my new diary with Royal AK Auto from Royal Queen Seeds. Day 1: The seed germinated on 4th day under 23 C and 90% RH. I put the peat cube into the soil right before the cotyledons came out. Snapped the end of the root (5 mm) while transplanting :(. One hour later cotyledons came out and opened. The shell was left in the soil completely. The stem is very strong. I like this seedling very much. Seems no damage was caused by broken root. Used 12L airpot, 10L soil-perlite mix, 2.5L of water with pH 6.3, 120 ppm. The soil is very soft and retains water very well. I had almost zero runoff after 2.5L watering. Performed Calcium test of the spring water I’m using. It’s 50 ppm. Good to know! Day 2: 130 PPFD, 9.4 DLI. She’s already asking for some light. Day 3: 200 PPFD, 14.4 DLI. She was pointing to the lamp like the light intensity wasn't enough for her. Increased light a bit. Progressing slowly, probably some damage was done while transplanting. At least she's alive :) Day 4: 200 PPFD, 14.4 DLI. She’s quite slow, although the first pair of leaves looks nice and clean. Stem is long, will cover few cm with soil. Day 5: 200 PPFD, 14.4 DLI. Added soil to hide the long stem. Day 6: 200 PPFD, 14.4 DLI. Today I watered the seedling till runoff to check the soil. I was shocked when saw 2200 ppm in runoff. Flushed with pH corrected water and FlashClean 2ml/l to wash out excessive nutrients. After 11,5 L of solution ppm was 370, although pH of runoff was about 7. What a stupid mistake to buy the soil without label. Hope she will be fine.
