Yeah ph was 6.5 when I started but will take your other advice on board when I start then next batch. May try just 2 next time to get it right as I have 6 ww seeds left.PH, 6.2-6.5 , calmag, good soil no nutes added in mix, extra perlite, light soil, and lightly water and keep wet every other day until they put off bigger leaves and then start letting them dry out before watering and start your schedule
