chelate nute???

Hi. I read something about chelate nutrients. My question is can chelate nutrients be readily absorbed at different PH levels?
for example : at 6.0 PH plants will not absorb calcium , what if my soil pH is 5.3 irrigated with calcium chelate ?
Another question is if I add calcium chelate to the soil, will the chelate bind to the soil's available calcium and make it more absorbable?
Sorry my question was so bad. but it is very necessary for me because in my country there are not many people who do research on this issue and I wrote this article quite hard with google translate ) LOL

Who told you plants can't absorb Ca below pH 6? I ran my DWC grows between 5.4 and 5.8 and never lacked for Ca in my plants.

Soil with pH 5.3 is not the usual pH. Most is around 6.5 - 7.0 unless it's had some acid added to lower the pH.

If you have calcium chelate then by all means go ahead and use it. Add some magnesium to balance it tho. Epsom Salts, (magnesium sulphate), is fine to use and cheap to while also supplying sulphur.
