Hello. Just looking for some information from growers who might have had the same issues. First off growing in coco for the first time. Never had these issues with soil. Also the Grodan cubes I used decided to start molding after 4 days. The paper on then anyway. Just the leaf picture.. only plant doing this. And the two in the front they are cookies kush, and are not filling in very well. And they are all growing very slow. Seeds germinated on 2-4-17. Using general hydroponics flora micro, flora grow, flora bloom amd cali-magic. I've got a blue lab guardian that is calibrated. Try to feed and just plain water at a pH of 5.8 to 6.2. Under 1200w's, air cooled reflectors 18-24"s away. I had co2 but the burner was a piece of crap woke up several times to the smell of propane. Room is currently at 558ppm. 18 on 6 off. Need any more info just ask. Thanks.
