I'd take a wild guess and go with anything chelated like calmag.ColdSmoke said:All fragile egos aside, what do you guys think is the most readily available source of calcium? Organic or not...

Roguejim said:Yeah, I've been hoping to find an amendment of any kind that I could work into the soil prior tp plant out, one that would supply adequate calcium the entire season. This season, about 6-7 weeks prior to plant out, I worked in both bone meal and lime, along with alfalfa meal and feather meal. I just picked a chile chilaca pod the other day with BER. Back to cal-mag for now, I guess.
Not since putting the plants outside. In another thread, I had some questions w/photos showing how my plants were suddenly yellowing after being put outside to harden off. With all the calcium-based NFTG products that I had been pumping into them, I started to lose confidence in the product when I saw this sudden yellowing. Scott Ostrander said my plants required even more calcium now that they were in the sun. He even thought the NFTG nutes had lowered my pH to the point where the plants weren't able to uptake the calcium adequately. My pH meter exposed that buffoonery. The pH was in the mid 6s. I had been using both the NFTG liquid calcium phosphate, and their liquid bone meal regularly up to that point, so I started to wonder...ColdSmoke said:Have you been using the the liquid calcium from NFTG?

No problem, but it seemed to work for me.
Just thought I would try something else this year as a comparative.
