Problems arising on a 2 month grow

I have two plants which are almost 2 months old. They were just transplanted to a sub's super soil mixture (using 75 FFOF/ 25 LW) and drenched with 11ml of azamaxx per gallon of water. They are being watered with RO and Light is Area51 XGS-190. What do you think? Cal/mag deficiency? or Nitrogen? something else? Thanks guys

Without Pictures or you explaining what the problem is no one will be able to help you.
