Ok, good details, carry on this way be slow and patient with the nutes. With regard to the light there is definately such a thing as too much light. A cannabis plant in full flower can use a maximum of 10K lumens, no more. A seedling can use no more than about 500. Veg uses about 3500. More than those amounts will easily bleach your fan leaves.

When we cut clones for instance we trim back the leaves so as not to collect too much light while trying to develop roots for instance.
