@HippieWarrior i appreciate the kind words but there's guys on here thats forgotten more about growing than I'll ever know but i love learning so talking about plants could never get on my nerves,I would say the yellowing is down to them being hungry,I've never used that soil but 6 weeks seems like a long time with no nutes,anything yellow will fall off but it's nothing to worry about just keep feeding them and let them do their thing!
