If I were you I'd transplant into a hotter soil unless your supplementing with liquid ferts. The guano is a good idea but you would want to add that to your soil and cook it for a month with other ammendments, like ewc, fish bone meal, bloodmeal, rocks (azomite), perlite and coco to keep it an airy mix, etc.
If you don't want to mix your own soil, I'd reccomend using vermicrop organics. They have a super light soil and a hot soil, vermasoil and vermifire. (Start out in the light soil transplant into hot soil later.)
If I'm not mistaken, the fox farms soil is connected with its fert line. Which is a chemical/organic line. Not sure if the soil itself will supply the nutrients your plants need for a full life cycle. I have grown in roots organics, which is similar to ffof, and had to supplement with liquid nutes during flower. Haven't had direct experience with the ocean forest but have heard that its about the same. But yea, this is why I suggest using HOT organic soil mixes, you only need to feed the soil and the soil will feed your plants.
Anyways sorry for ramblin on your page your plants are looking very healthy, nice start to your first 1000w grow. + Rep
