Problems starting out

[aaronmndew]

I just recently started a few plants with the bubbleponics system. My seedlings are growing very slowly. The one that is growing the best has very wrinkly leaves. I also have a lot of white buildup that's coming from the system. It's building up in my tubes and all over the starting Cube. I was wondering if the slow growth was due to not having good enough oxygen stones. I ended up buying cheap ones from Walmart so I don't know if that's my problem or if it's an issue with my water being too cold. I don't know if growing during the winter is a good idea or not. I do have a heater and my room stays at around 70 degrees. Any advice would be appreciated thank you.

I don' think cheep stones are an issue. How much air are u pumping I pump 250 gph into each 1 of my pots.
The white build up could be salts do u use top feed.
