Shocking pale green new foliage on most of

my pot grown or grow bag dwarf tomatoes. Just remarkably fluourescent, bright green - anyone ever seen this? thoughs on whether it is just a phase the plants are going through, or signs of trouble?

The past week or so it has been rainny and no sun. My plants all have light bright green new growths near the top.

Yesterday and today, the sun came out and the leaves turned a darker shade noticeably.

Have you had a ton of rain lately? A few years ago, we had torrential rains nearly everyday for a week or more. My plants all turned a shocking shade of neon green. After a few partly sunny days, the plants returned to normal. I didn't notice any growth delay or other damage associated with the neon weirdness either.

The pale green foliage cleared up on pretty much all of my dwarfs....except that many of the Sneezy F3s are showing something quite different - nearly white foliage in the center. Pics here.

"Sneezy F3s"

Look at photo 255 here:

You could try a teaspoon of epsom salts in a gallon
of water on one of them with this symptom and
see if it goes away. (Probably won't hurt it any even
if magnesium deficiency is not the source of the
mottling, though it may raise the pH some.)

Actually, once it heated up, with the exception of 3 of the dwarfs, they look great. And, on those three, there is some white growth in the center - and I mean white! I will have to see what gives over time...

This site seems to have better pictures of tomato
leaves and more detailed explanations:

(Your Sneezy picture looks a lot like the nitrogen
deficiency photo at this URL, except for the veins
in the leaves.)

Re: my previous comment, note that *excess* Mg
can reduce Calcium uptake (think BER later). I was
reading a page on remedial treatment of golf course
sod where they added lime to a high pH soil to correct
a problem, not what one would expect to be the
solution. The magnesium in the soil was responsible
for the high pH, not excess lime or some other calcium compound, and the sod was having difficulty taking up
enough calcium to remain healthy.

"More kelp!" (The shotgun approach; kelp has something
like 73 trace minerals, so whatever it needs is bound to
be in there somewhere.)

Hope the problem clears up for you easily.

Hello-
I've never introduced myself, I'll make that another post.

I have the same problem on about 5 of my 30 plants. I was hoping that the plants had just done a lot of growing overnight and had not been exposed to the sunlight. Is that ridiculous and should I start worrying? Aside from the pale foliage the plants are growing beautifully.

Sigh.

Ok... I think our problem may be iron deficiency. My plants look exactly like the photos I've seen of tomato plants with this problem.

Soooo... I need to add iron? I have Green Light Iron & Soil Acidifier. Anyone have any experience with this?

Hello neighbor. I had the same issue on one of my potted tomatoes that had a different soil mix. Added a little watered down Rose fertilizer and it cleared up in a couple days.
