If it looks like its just powerdered on there, it probably is mold. A fan will help you with that, as well as not misting!

Plants 5 feet away from a 1000 w light recieve less light actually than a plant 1 ft away from a 400 w! It looks bright, sure, but the usable amount of light for plants drops drastically the farther away you get. For a 1000w at five feet, your plants are receiving less than 1200 lumens per foot! Your absolute minimum should be 2000 lumens per foot for growth. Right out of the bulb (less than one foot away) The same light has over 9000 lumens. Read up on some of the lighting threads to get a better understanding of how to make your light work with your plants. Heres a good one: http://boards.cannabis.com/indoor-li...uch-light.html
Just lower the light to about 2 feet from the tops and check your canopy temp. Do you have a reflector or hood for it?

Yeah being serious about the misting. Your humidity is ok so I wouldnt worry to much about misting them everyday. Clones might need it, seedlings if it is super dry maybe, but not vegging or flowering plants.


Coco is a different growing medium, so the nutrients have a different chemical composition to react best with Coco coir. A new fert. for soil is going to be needed sometime to make sure you avoid lock ups and other issues.
