mate all i can say is i am not shore of what all the stuff u r useing is.Sounds like a lot of work.if anything the ph could be a little low,keep it simple.i dont soak my seeds.I let them sprout and those fist two funny looking leaves they contain all the food they need for at least two weeks.I give them half strength fertilizer (grow type) after 1 week of sprouting then they should b ok to go to full stregth after 3 to 4 weeks.I never have any problems.also make shore u r not over watering or over feeding,could b a simple as a nutrient deficency.not shore if i have helped.happy growing........
