That long black thing is just a piece of dust the other pictures are just normal looking parts of the plant. There is nothing that looks worrying in your pictures. Speaking of pictures, that purple light sucks for showing what your issues are, please if you can take pictures in normal lighting so the damage is easier to see.
I would be leaning towards a magnesium deficiency. When I run BioBizz products I tend to supplement with a little Sweet from Botanicare which is magnesium sulfate, I find it keeps the Mg deficiencies to a minimum. But I said this in my first post on the thread.
The other thing it may be is simple over watering. Water only when the soil is dry enough that it needs the water. If you are giving the plant water before the soil is dry you will be depriving the roots of the oxygen they need to make your plant thrive.
Again, the Top Max is a bloom booster, its only needed in the flowering phase of the plants life. In veg you should be using BioGrow (or Fish Mix), Root Juice and Bio Heaven, plus I add in Sweet. I also like Photosynthesis + from Microbe Life Hydroponics, its a broad spectrum microbial inoculant and works wonders on plants.
