Hi

Are they growing in a greenhouse ? the reason I ask as it look like water droplets have been left on the leaves in full sunshine and they have been scorched.

I may be wrong but will be interesting to see what the others may have to say

That was my instant thought too GG water left in leaves if full sun and they've been scorched. Hank always water your toms. in such a way the leaves do not get wet.

Thanks guys, much relieved. Could have been water before I started watering them more carefully. It was on the bottom leaves only and now they're about 2 ft tall.

Hi Hank

Try and water just the soil , at least we all now what it is now, only cosmetic wont effect the crop.

Sorry, I may have replied twice as my reply didn't show up when I checked just now.

Looks like salt residue from fertilizer or something that splattered on the leaves. If so just spray it off with water or wipe with a damp sponge.

Thanks all, job solved I think.
