Six months on 24/7. How big you going to grow that Xmas tree. When do you plan on flowering ? I'm not sure of the problem, yellow under leaves and on tips. A picture is worth a thousand words and will get a great amout of help. when we can see it so much easier. Six months of veg and I'd have a 12 foot tree. Also what type soil and nutes will help.

Ugly Plants My little babies turned yellow on the underneath leaves.One of the other plants has a hint of yelow on the tip.The lights that are used are fluorescent plant lights and a super bulb ballast system.We were told for the first six months of plant life to leave the lights on 24/7.We did lightly fertilize a few days ago.Perhaps too much water? Thanks in advance.. Rating: 5
