[rastaman79]

hello peoples, after searcing the site, i haven`t come up with anything.it goes like this...got brown metalic spots on about day 21 of flower,im using tap water that has been left to stand and ph`d to 5.7,im using the canna bloom 2 part,i check and adjust my ph daily, res change every 9 days. also i have plants all in the same tray and its only happend to one plant,so i think calcium def and bugs are not the answer,just come across something called "ozone damage" and as it happens i had a uvonair running next to the plant with damage for about 24 hrs solid as i didnt know how long to run it for,( the uvonair is a odour neutraliser and it generates co2) could this be the problem? its off now and will be till i read up on it.i will post pics if i get enough intrest.all help appreciated,peace,RM.

sounds like your on top of it.

I've not seen this myself, but my 1st rule when something goes wrong is "do something!"

Im amazed at how ppl will just watch a plant dry up. The whole time spent trying to figure out what to do.
