The leaves started showing signs of turning brown at the tips, and curling upward, at day 22. I had moved the Jiffy pots to 6" pots (using same type of soil) at day 15.
I can't tell if they are N-deficient or what. I use 6400K CFL bulbs about 2.5" away, getting about 3000 lumens/sq. ft. One bulb for each plant. I water sparingly to not drown them. Fan on constantly. Lights on 18/6 cycle. Temp a steady 26-28C. Humidity 69%. Using Northern Lights seeds.
Here is a photo of one plant. [I hope this shows up. It is not showing up in the Preview, but the URL is there.]
I started thinking about the Jiffy pots. I stuck my finger in about an inch today and could feel the side of the Jiffy pot. So it seems like it hasn't dissolved like I had expect. Is it possible that the Jiffy pot is restraining the roots?
Any help will be appreciated. This is my very first grow. Growth is very very slow. At day 25, maybe 3" tall.
