Hi Indimaniac,

Here's where I'd start..

1. Lay off any fertilizer you may be adding.. from what I read it seems like FF Ocean Forest already has some in it from the additives. I'm fundamentally against this and why I use soilless mix vs. dirt.
2. I wouldn't place too much emphasis on soil pH as I think measuring it accurately is difficult at best. What I do is check and adjust the pH of what I'm putting in every time before adding, water or nutes. Generally what you see is the pH creep up as the water sits in the containers and it's best to take it back down.
3. The idea that you have any sort of uptake problem at this stage is just wrong.. these are way too young.
4. Those ugly leaves on the new ones aren't nearly as important as the next 2 sets.. give it a week here and see how things are looking.
