This is my first year trying to grow tomatoes and there is a LOT of info out there. Sometimes it's hard to sort through it all so I'm asking for some help.
At the recommendation of my local nursery, I used BACCTO potting soil to plant my tomatoes in my containers. While Googling BACCTO today I came across a statement on their site that says tomatoes will need additional calcium when using BACCTO soil.
What is the best way to add calcium? What source do I use for calcium? I just transplanted the seedling to the soil and pots a few days ago and now I'm concerned about the calcium issue.
