Veggie seed starting question

Collegedale, TN

Hi;

I posted this question on another forum before I discovered this forum. So, I'm hoping that I finally have it in the right forum and someone can help me with this!

I am starting my plants for spring now and have a question that I hope some one can help me with. Last year, I started broccoli, cabbage, and cauliflower indoors in my basement under grow lights. They came up wonderfully but after they were about 11/2 - 2 inches tall, the leaves began to curl back and it looked like they just dried up from the outside in. The small leaves in the center weren't affected at first but they soon got this too. It ruined many of my plants. When I noticed that this was becoming a big problem, I took the plants outside to my greenhouse and the problem stopped. The new leaves that came on were fine. I was thinking this may be damping off but after reading about it, I don't think so. On the plants that were hit worst, the stems stayed very sturdy, even after all the leaves had dried up and died. (It really looks like they are drying up. You can touch the affected ends of the leaves and the ends will come apart like dried herbs.)

Now, I don't want this to happen this year and I don't really know what I am doing wrong or what I can do to prevent this. I have looked for a long time around the web and just can't find anything that deals with this. It seems to affect only the plants like broccoli, cauliflower, and cabbage. My tomatoes were totally unaffected by it although I did have a little trouble with my peppers as well. Can anyone tell me what this is and what I can do about it? Thank you so very much!

RAphael, I'm sorry but not surprised that no one on the WS could answer your question about your problem with sowing veggie seeds under lights. On this forum we don't "do" sowing under lights, only outside in the elements with Mother Nature as our guide. I wonder if the Beginner Vegetables forum could help?

Hi,

I'm going to take a guess that it's too warm & dry under the lights. Most veggies and a lot of annuals need cooler growing temps than when germinating. I move most of my stuff to the greenhouse as soon as the 2nd set of leaves form.

Before I got my greenhouse, I had my tomato seedlings under lights and I had to be careful of the distance btwn them & the lights. I swear they grew 2 inches a day. If the foilage is too close the lights will scoch the leaves

Hi;
Thanks for the suggestions. I have started monitoring the watering more closely and hope the problem goes away eventually. I'm hoping to get these out to the greenhouse this weekend, so I may still save many of them! Thanks so much!
