curling leaves on top of plants

#619459 - 04/20/12 09:19 PM (12 years, 11 months ago)

Hello

We have 11, 2 week old plants. They started from seeds with a mixture of sunlight and a 20w flourscent light. We now have them under a 600w Metal Halide light for the last three days. they have been perfectly healthy as seedlings and for the first two under the new light.

We are using Miracle Grow Potting soil with a little worm casings, and they are on in 3 gallon pots. The temp usually runs right around 74-83 and the humitiy is 30-40 we are trying to raise that number.

There is only three that are having this problem. 2 of which are curling only and the third has brown going through the veins of one of the newest grows. I'm not sure what the problem is but have provided a picture to help you see what I see.

I appreciate all the help you could provide to a first time grower.

They still look like they maybe getting worse I have a bunch more pictures to show you this time around. I got the pH right around 7.5-7, they are slowly dropping. The yellowing seems to be getting worse and the curling seems to be getting worse on the ones that were already curled. New growth seems fine to me. Let me know what you think.
