Hey,
I just posted on another persons thread.
Similar problems to you. Maybe this might help you too.

I will admit that I am fairly new to this game and learning as I go along but I think I found an article that might help you figure out what wrong.
Have a look here and see what it most closely resembles. Plant Abuse Chart and Photos by Nietzsche

I hope you find what you are looking for in there. I think he/she did a good job in pointing out the main problems.

This deals with deficiencies and overdoses and not parasites.

I also have a grow going on and your feedback would be much appreciated.

Its here : LED LOGGER

I hope I may have helped in some way.

Take care
