Greetings Rollitup !
I have a question regarding my 2 week old plants here in DWC buckets. I am running two plants in 5 gallon dwc buckets. One of them is under a 120w LED and the other CFLs. I am noticing that my dwc plants have some leaves that look twisted and deformed...more so the one under the LED. now these according to my research are signs of heat stress and/or magnesium deficiency...it could also be a gnat infestation according to my research. I am trying to find out which of these is the problem or if it is a combination. I have been feeding 1/4 strength nutes and no other signs of deficiency are apparent so I doubt its a mag deficiency. There was a noticable gnat problem during the summer but it has since died down significantly since I used yellow sticky cards and Dr. Bronners soap. I am thinking it is most likely heat or light stress. I moved the LED higher away from canopy level and it is now at about 12" away. I also noticed some small openings at the side of the sliding doors and thought maybe some light could be pouring into my closet during dark hours...could this be the reason for the signs of stress on the leaves?
I have attached some pictures of the twisted leaves of the plants below...hope they help in identifying the problem.
Thank you in advance for any help!! Rollitup forums has always been a great help in the past. =) Peace everyone!

and thanks to everyone else who replied. I will take the PPMs into consideration and will be looking into buying a meter. Thank you.
