please take a look thanks

1) PICTURE OF PLANT *** VERY IMPORTANT ***
2) Growing indoors
3) aerogarden set for tomatoes
4) aerogarden sponge
5) 12/12 from seed and looks like it is beginning to flower

It is on 2 different plants. It started on 1 and now it is happening to the other. 1st pic is of first plant it happened to and 2nd pic it is beginning on other plant. It starts out as spots. I was on just water when it started on lower leaves and thought it may be hungry so used 1/4 nutes and it started happening to newer leaves and 2nd plant which is a week younger. It starts out with little copper dots toward the middle of the leaf. As it progresses it almost looks like green paint is about to chip off of the leaves and now it is dry like paper. Can anyone help?

How long ago did you give them the nutes? Also, why are they on 12/12 already?

I game them nutes on 12/21 and there was a nice growth spurt but the older growth kept getting the spots but even worse and spreading to newer growth. So on 12/25 I went back to distilled water. Still on distilled water and I check the pH every day. I don't know if theyre hungry or what and I am scared to feed em.

I am on 12/12 because I am using an AG and limited with my height and wanted to see what would happen. The older plant sprouted about 22 days ago and is already showing sex and stinking up its room.

What kind of water were you using before? What kind of nutes are u feeding them?

Always distilled water from the beginning. I am using the technaflora recipe for success.

Do you think it may be phosporous deficiency? The stems are kinda reddish purple and the new growth has a purplish color too it too as it comes out. hmmm
