Nutrient Deficiency

This is a pic of the Big Jim that I am keeping alive this winter. This leaf curl has been going on since it started to grow new leaves and i am just curious to know why they are curling. It is only happening to the older leaves. They eventually dry right up and fall off and the plant is producing alot of new foilage and buds. Does this resemble a deficiency of some kind?

Dale looks to me like sun deficiency. No seriously now I'd check your nutrient solution ph when your feed your plants and set that closer to 6. The small leaves and the yellowing around the edges makes me believe it is a nutrient lockout. Just one growers opinion to another.

PRF, it very well could be a lighting deficiency this guy gets almost nothing, I just want it to stay alive not get big. As far as the Ph I have never really worried or wondered about it until reading the habmans thread. I think I may get a meter and start checking. Any suggestions on a meter?

Ya, I think it needs more light. When you cut it back, did you cut the roots back too?

1. Is it the light, or are the upper leaves mottle or pale on the margins? That could be a magnesium deficiency which can cause leaf curl, but not always. I think a calcium deficiency is about the only one that might cause that amount of leaf curl, and that usually starts with the newer leaves, not the older.

2. How is you aphid or another uggy buggy situation?

3. Or, let's not forget: Physiological or Nonparasitic Leaf Roll:

Physiological leaf roll occurs during wet weather or when transplants are first placed outside. Typically, the leaves roll upward, at first appearing cupped but eventually rolling continues until the leaflets overlap. Overall growth of the tomato is usually not affected. Fruit are not injured by this condition.

Another type of leaf roll associated with climatic conditions is called" nonparasitic leaf roll". (Note: Physiological leaf roll is also nonparasitic). Nonparasitic leaf roll is considered to be caused by an irregular supply of water or severe pruning. It is a temporary disorder in which the edges of the tomato leaves roll upward and inward, even overlapping when conditions are severe. Most leaves on the plant are affected but the condition is temporary, with the plant assuming normal growth habit within a few days following pruning or irrigation.

Yes, the roots were cut back to almost nothing as was the top.

There are no aphids or any others. Actually after taking a closer look the leaves seem to get yellowish on the tips and they also get completely dry before falling off. Most all of the leaves are showing this. I think I will boost up the ferts and see what happens.

Just make sure the fertilizer you use has all the micronutrients. Not all of them do.

Hey Dale my ph test kit consists of a small vial that I put 3 drops in and match color to get reading. Just a couple dollars gets you this kit. What you can do is water that plant till there is water dripping from bottom and check that. Meters are expensive and you will want my kit as a back-up anyway.

Hate to bring up this old thread but my Big Jim is showing different signs. Notice the spots on the leaves they are not any different color just transparent. Anyone seen anything like this before. The yellowing is just from the lights. This thing is starting to grow like crazy even with the problem it has.
