Can anyone help me understand what is going on here, I’ve had this problem before but not for a couple years. The new growth leaves have been closed in tight on each other (see photo) for a couple days and growth has stopped. In the past when this happened I couldn’t figure out the issue and they never recovered. Right now I’m growing 2 plants, each a different strain and both have the same problem which makes me think it’s an environmental issue. My temps are consistently between 75-80 degrees, humidity stays between 49-60%. I’m not supplementing co2 but the levels are between 850-1000. Any insight would be much appreciated. Thanks.
