First time indoors(may need advice)!

I am a long time outdoor grower and a very inexperienced indoor grower. I am officially working with 2 sour diesel plants from clones that were started using the water cloning method, Currently I have a small 4'x3' grow room made out of some OSB (particle board).I ran a 65w Flourex CFL until I bought a 150w HPS which may have gave my plants a bit of a culture shock, since half the leafs looked brownish in all different spots of the plant. I use Fox Farm brand fertilizer, I have all the liquid fertilizers they sell for soil including the soluble granular fertilizer which I am very uncomfortable using since some of the NPK numbers are 9-50-10 and I never really used them before.I am including some pictures of my plants at week 5, and I would really appreciate some feedback from all of you in my first attempt to grow indoors.
Thank You

I would not use the granular fertilizer on indoor plants, as they are very unpredictable. Using them on a large outdoor plot would be more permissible than using them in closed containers.

It looks like some of your leaves are showing signs of Potassium deficiency. But before you start treating for a K deficiency, make sure it has nothing to do with pH of the soil or water.
