Hey guys. Im new to the site and this is my first post. Hoping some of u guys can help me out. I guess ill start by giving some environmental details. I recently had to move into tents due to space issues and im currently growing in a 4x8 tent. Space juice from solfire 20 clones about 2.5 weeks from transplant in half gal pots coco/perlite 70/30. Fed once per day 1.7 ec 5.9-6.1 ph to a little runoff using jacks part a and part b with some epsom. I have 2 3x3 tents that i plan on moving some of these plants into. Right now they are growing under 2 hlg 600r’s 36 inches away from the canopy and i have the dimmer set to the 3rd setting, which reads about 21,000 lux on average throughout the tent according to my cheap uni-t lux meter. Temps and humidity are steady between 78-82 deg and 58-65 rh. Fans for airflow. I have been getting orange or brown leaf edges that seem to continue to get worse while all of my new growth seems to be nice and healthy. I have been going back and fourth between deficiencies and possible light burn? I am just not really sure and wondering if any of u guys have dealt with this before. I have a few grows with these lights in a room setting and never had these type of issues so im just not sure whats up. Ill throw some pics up. Thanks in advance for any help.
