Hi,
Started my first two dWC grows, well one is in an aerograden ultra auto berry lowryder n sweet tooth then the other in a 3 gallon bucket with hydroton and plenty of o2 pumped into the water in both
Fox Farm GrowBig Tiger Kangaroots, MicroBrew, and Super thrive in both settups. did a flush w/ sledgehammer on bucket an hour ago and changfed fresh nutes n water ohh water is a tiny bit tap n mostly bottled delivery spring water that pretty clean when ppm checked reads like 5 before nutes ph in both from 5.0-6.8 averaging upper 5s

It began in the bucket first which has a clone of a blueberry in it the others were seeds.. It started with these little tiny brown dots that get larger and eventually yellow it starts on the lower leaves and as new ones develop, it evenntually starts on them... so far in the aero garden it began on one of the 3 2week old plants,,, the buket is about a 3 week old clone

pics are of bottom leaf i pulled last pic is using a usb microscope at nearly 300xIMG_4106.jpgIMG_4107.jpgIMG_4108.jpg20131130022703.jpg

please help dunno what to do everything i read says either calmag defiency, fungus, or mites, dont see any creepy crawlers any where plus i keep it clean and vacum all the time and have a hepa / germicidial air cleaner running full right by the grow box with the bucket and the aerogarden ontop of the grow box... save my babies, well they do keep gettung new nice looking growth but when the next growth comes it begins on the last growth and so on the white spots idk if they asre the plant or my lens becayuse u dont see them normally

help much appreciated

It is Calcium deficiency, flush (one week) and re-adjust you feeding (lower amounts). What type of nutrients are you using? How old plants? Growweedeasy.com has good pictures of as well as roll:-P it-up
