ruan1980 Posted November 26, 2012 Report Share Posted November 26, 2012 I've got these brown spots on the leaves and as you see they are looking really sick. The bigger on is over a month old from germ and the little one has the same traits and is a couple weeks germ. I haven't had this problem before but I recently moved to a new setup and I have changed to RO Water. For the little one I only add PH'd water and a bit of aussie tonic, for the bigger one I have PH'd RO water, aussie tonic, 600ppm jungle juice 3 part. PH is 5.8 for both, 70f degree avg temp, 40% humidity. I have cuttings in the same room which are all healthy. I just cannot figure out what it wrong with these little girls. I thought it could be a potassium def and flushed and increased potassium, which didnt seem to help because the new growth still went brown around leaf edges. Also, I thought my de-ionized RO water was cause problems so I cut out the de-ionizer with the RO system and flushed. This has been 4 days since I did this. At the same time I thought maybe the RO water was causing a manganese def so I added 1 parts tap water to 5 parts RO. My nutrients Jungle juice grow, micro, bloom, 2ml/l green planet procal beneficial bacteria aussie tonic 600 ppm total. Could aussie tonic be cause this? this is the first grow I have used it, also first grow I have used RO water. thanks Quote Link to comment Share on other sites More sharing options...
