hi I have seedlings about 2 inches tall they look like sunflowers. what can I feed them to thicken up the stems thanks for any help.

thickening can be helped by using oscillating air and silicon supplements, when plants bend in the wind that sends signals for growth, I see it all the time.

Would love to see a pic of a fig seedling 🌱

Have pictures?

is it hard to post pictures. I now have a small fan on them I was thinking bone meal might thicken up the stems  the seeds came from Greece. I can take pictures if I can figure out how to post them thanks Guys.

Oscillating air is better than direct air. If not oscillating then make sure the fan is far enough away to slow down the evaporation process and not put to much air on the seedlings.

turned the fan off till I get it set up better.
