| This morning I noticed my healthy looking seedlings showing their cotyledon leaves curling and totally drying out to the point that if I squeeze them they start to crack. They were pretty close to my 4 40W Daylight Flourecents however that has not been an issue before. The only change I have made this year is they are in my basement(totally sealed off by plastic as I did in my loft the last two years) I have my electric heater keeping the temp between 75 and 80. These are 10 days old. I moved the lights away about 2-3 inches now but I dont think that is the problem. I am using the same soil-less medium I used last year(grow plugs) which worked great. The true leaves seem to be unaffected at this point. Thoughts? Is it doo dry? bring in a humidifier? They have plenty of water so thats not an issue. Tks |
