CBD Mexican Auto-flower

The 3 plants have been outside for a week. They will be supported with extra strong tomato cages. Windows were used to protect from the prevailing winds. They are growing but are spindly, as in, big distance between leaf junctions. I wonder if I should have topped the plants, but I have read that auto-flowering plants don't do well if they are topped. They vary in height between 9 and 12 inches. In spite of it raining 4 days this week I have been able to give each plant a liter of water with nutrients. On the sunny days it has been very warm, reaching 30 C.
