Try and find some white rock.....marble or not....dont let the paper get wet it will mold on you and could threaten your tomato harvest.

On our tomato plant....you have one main stem. then your leaves.....at first, single blade, like now, then three fingers and 5 and 7 and so on.

Those fan leaves meet at the main stem on opposite sides. IN the tiny nook or crevice between the main stem and the leaf stem...is your site of future secondary growth.

It is the plant matter that will emerge from this spot that creates all growth other than just a main stem with leaves.

It is where the growth emerges that will form all buds, all clones and everything else.

It is the secondaries that make or break a yeild. IN fact, the main kola is nothing but a whole shitload of secondaries grown close together to form one bud.

All buds come from these sites.

When your plant is mature, the leaves from the main stem will fail to grow directly opposite one another and will instead grow at alternating levels on the main stem and on the now long secondary stems.

Hence the alternating nodes that identify the maturity of the plant.

In the attached pic, you see the main stem...then you see the fan leaf stem and then right in between in secondary growth.

This is a 5 day old seedling....with proper lighting and reflection, you can see secondary growth on a seedling 5 days old emerging.

You need GREAT KELVINS to get these so early...but this is where you want to focus your plant energies and lights and get these sites going at every node your plant has.

These are where your branches are formed and all other growth comes from....otherwise you wind up with a stem and fan leaves....
