http://forum.grasscity.com/indoor-grow-journals/792298-1st-grow-journal-raskal-og-11.html Look at the pics of my mother plant...This is happening to the plants in my flowering tent too... I thought it was just Calcium def so I watered a few times with Cal-Mag but no luck... any ideas?
Nute burn. You really need to give more detail to get help with plant problems but those pics are pretty unmistakable. That last pic does kinda look like powdery mildew as well.
Ok well. I guess I should give them ph'd water only for a few days? As for the powdery mildew, I can get rid of it by foliar feeding 1part h2o2 and 3 parts water?
