Okay so the plant is 18 days old. Its an indoor grow with florescent lights 5 daylights x 30 watts a piece. They are in Fox farm ocean floor soil. Im starting to see slight yellowing on the leaves and on the tip of one you can see browning and crisping. What can this problem be? If any? Let me know. Pics Below
You can see Browning here ^^^ maybe nitrogen defficency?
