good evening all. I am currently running some tomatoes on a 4x8 table, the plants are about 4 weeks old and beginning to show some little buds. after working in the garden today, i noticed that the stalk near the hydroton appears to be weak and much thinner then the rest of the plant. Could this be due to a lack of mechanical air movement in the room? ( i did not have an oscillating fan in place) or do i need to just add some more hydroton to beef up the support? Or both?
