Hello everyone! Iā??m somewhat of a newbie that has limited cannabis growing experience. However, Iā??m a longtime organic propagator, gardener, and cultivator of just about anything that can be eaten. Additionally, I have been a lurker on this (and other) forums for quite some time.

Iā??m trying to determine if I actually have a problem or not. My seedlings have curled under leaves, but otherwise seem to be OK. No discoloration of leaves or other obvious symptoms. I have searched this and other forums and have garnered a myriad of possible causes, but nothing definitive. See attachment photos.

As of today, theyā??re 9 days old in starter mix with nothing but RO water at about a ph of 6. No nutes yet. Theyā??re under three 26W (100W Equiv.), 6500K CFLs hovering about 4ā? off the upper leaves. Temps have ranged between 72 and 81, but mostly around 76. Good air circulation with small fan and fresh air. Humidity fluctuates between 27% and 45%, but usually is closer to mid 30% levels. Iā??m finding a conflicting number of possible answers ranging from nothingā??s wrong to too cold, to too hot, too close to lights, or too much light. Iā??m trying to catch a problem before itā??s too late.

Any input would be greatly appreciated. Thanks!!
