Curling tomato leaves

[platinumethics]

If the leaf curling is common and not something to worry about, I will be relieved. I went ahead and got Micro today and changed out the reservoirs with fresh water and the proper nutrients now. I did a light nutrient mix so that maybe they will get better in the next few days.

Hi everyone, I have been following this discussion with interest. At times I have had the same things happen to my tomato plants. For me, it has been strictly a nutrient issue when my leaves curled. I am mixing about three tablespoons per gallon.

On another note when my water temperatures got beyond 75°that caused a problems as well.

Just my 2¢

Anytime you want to contribute information....I will always appreciate it!

I'm noticed on some other grower's posts that they have the curling then change their nutrient solution and the leaves uncurl within a couple days. I'm not seeing this happen with my plants. I will just have to minimize all the possible problems until I find the issue, unless it is lighting that causes it from what ProZachJ is saying, since he has more experience with led lighting than I do.

I'm not seeing any discoloration, spotting, abnormal wilting or other negative traits as of yet.

Waiting with bated breath.

After a couple weeks, I started noticing that my 90W LED light wasn't sufficient to provide coverage for more than 2-3 square feet. Very disappointing. However, one positive was the immense vegetative growth I got from the plants was amazing with the light at the correct height. I have since moved my plants outside because they have grown too large for my 1 UFO to provide for. I am going to begin a new grow experiment this time was only one plant under the light. I am optimistic about the results.

Coverage is also highly dependent on the height of the crop. Growing a bush type will allow use of a lot fewer lights than an indeterminate tomato. I've found for a 4x4 tent that 4 UFOs is enough for a decent go at most crops.

Yeah, I believe if I do another round of these plants I'd only do one under the light and see how far I can get. I lost a lot of plants in the move due to branches breaking under the weight of the plant so I know now either never move them or make it much more user friendly to move.
