too much fertilizer

Ok. How did you come to that answer? They are controlled sizes of fertilizer tablets. So how is it to much fertilzer?
are you basing this on the fact that the plant is smaller than the usual cherry tomato plants that grow in the garden? Should I skip next weeks feeding? Drain the water in the water basin and add half as fertilizer? So far it has sprouted the seeds, grown them fast like its suppose to. Thus the reason it is a great garden. But they just happen to be yellowish with green veins now. Since you cant grow tomatos in south Fla in the summer outside. This is the only way to grow tomatos. I know these are a curiosity, but I wanted to grow them. The cherry tomato that usually grows in the garden, is about twice the size and half the amount of fruit, but bigger. So...any hints on how you came to that answer? Thanks

I suggest you contact the manufacturer of your machine and see if they can advise you on whether or not Micro Tom will grow properly in their device.

Also, search this site for Hydroponics and you may find others who have used the device for varieties that are not sold by the manufacturer.

Otherwise, I would remove the plant and place it in a small container filled with potting mix and set it in the sun. If it recovers,.....

I've got 12 plants growing. That is the advantage of growing this micro Tom in the AeroGrow. They are so small..I can grow more than just the 3 that AeroGrow 'lets' you grow in their tomato kit. but their tomatos are much bigger cherry tomatos. Cant just pull them out and put them in soil, they would die for sure. The roots are grown into the sponge they are growing in. I am going to cut back on the fertilizer next Monday when the next feeding is due. and if they dont green up in another week. I found a lot of Micro Tom tomato seeds for a VERY fair price. So if these dont do good. I'll try again. Or plant in soil and grow them under the lights, and not use the water part.
