I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

I'd say Calcium and Magnesium deficiencies.. Possibly some Nitrogen as well. How much have you been feeding? I don't know what promix m is, so i can't say if that will help.
