Hi these autos are 10 days old and look like they ...

For me.... my issue was the light was too far away... seedlings should be like 24-36 inches away it says... vegetative18-24....flower12-16 or something along those lines.. every flower and strain is different...... possibly too much water as well... hopefully helps u out

There's almost no info in the diary for me to go off of. How far is the light from the seedlings?

Move your light closer and they will stop stretching. Until they mature more, you can use just about anything to support them. Aim for 400 ppfd. Find your light on Amazon or another store and look at a ppfd map (looks like a grid with numbers in each square). This will tell you how far you should hang your light. Go up to 600 ppfd after week 2 usually-- when they are put of the seedling stage.

Top up cups to help support. When you transplant you can plant them with the stem in the substrate. 👍👍 From The 45th&47th President Of The United States Of America

I used a pencil as a stake with my seedlings for about 2-3 weeks. Lose fabric tie around the stem and pencil. They will be fine if you give them plenty of light. Maybe move them closer to the light
