That Ocean Forest is a hot soil from what I'm told and provides a good nute base to get your seedlings up and running. Some guys have said 3-4 weeks worth of basic nutrients to get the veg process going. I used the same soil for my 1st and only grow so far. For the first few weeks I strictly started with a 2mg per gallon Cal-Mag+ additive, no other nutes. I set my PH to 6.5 and was off to the races. My first few nutes were Holy Mackerel and Kelp Me but I was and am still a noob when it comes to the NPK checks and balances. A few more weeks into veg I switched to Humbolts Secret A & B and have stuck with that. It almost always PH's perfect once mixed and my plants have really responded well to that and Cal-Mag.
I will say I had ONE of my 5 look just like yours, and around the same age too. I wasn't sure if I shocked it when repotting, or if I pissed it off when I placed her in the tent. Until I had my tent setup I would take the ladies (all 5) out into the natural light and although they all loved it one just started to wither before my eyes. In the end my tent did not have room for 5 so I put the sickly one outside and on plain water it quickly recovered and outgrew her 4 indoor siblings. Here is a pic before (middle plant) and one from a week ago.
