Probably lack of sunlight. Plants in pics look pretty healthy. How much sun do they get daily? What about watering?

The crucial point in your other post was that this plant was supposedly "several months old" (so it is really approx. 1 1/2 to 2 months old, correct?) and only "18 inches tall". That is the real problem I fear. A Celebrity, even tho it is a semi-determinate variety, that is even 2 months old should be much bigger plant - at least 3 feet tall. This is especially true with all the feeding you have given it. Now I see the problem. (1) Compacted soil - it sounds like you didn't use a soil-less potting mix but maybe used Miracle Grow Garden Soil for Vegetables. Correct? It is not intended for use in containers. And (2) no holes for drainage in the container so the water "collects in the bottom", correct? Size of the container - if it is a 5-7 gallon should be fairly ok but the combination of poorly draining soil and water collecting in the bottom of the pot which causes root rot may explain the small size. And the very stressed plant with the high temps explains the blossom drop. My suggestion would be to find a bigger container that has room for you to add some good quality soil-less mix to and still have room for this plant and then transplant this plant into it. Make sure it has drain holes in it. I'd pinch off all or most of the current blooms - they aren't going to amount to anything anyway so no loss - and keep it in the shade for 3-4 days. I think you should see a marked improvement in the plant within that time. Keep the plant alive and healthy until the air temps cool and you'll get some fruit set. I hope this helps get you some tomatoes. Dave

i doubt it ... more like individual cells burst.. which sometimes happens with excess rain ... i am pretty sure there is a tomato forum .. where the real T kooks hang out.. lol .. just keep in mind.. about 99% of that leaf is still functioning ... so at this point its only cosmetic damage ... and i am thinking.. those are the lowest.. oldest leaves ... what do the newest growth point look like ... that is where i look to see the vigor of the plant .. or the newest of the bug .. if any ... ken

looks like vermiculite.. but if you want my 2 cents on growing media (for seeding or just potted plants, personally, i recommend coco coir for seed starting. around here i can get organic coco bricks for $13 and is enough to fill an entire wheel barrel. for a seed starting mix i add a bag of worm castings (or 3 parts coco, 1 part worm castings). the Walmart around here sell 5lb bag of worm castings for $4.50. the results is a mix that is superior to any premade potting/starting mix you can buy and total cost is less than 20 dollars.
