Re: Newer leaves turning lighter
I really don't know how long it takes to see results from adding calcium -- at least a week because I haven't seen any obvious results yet and I applied a foliar spray and gypsum almost a week ago.
Even if the roots are deep, the calcium from the gypsum or agricultural lime should eventually get down there. A foliar spray should act faster. I used a calcium chloride spray sold for tomato blossom end rot (also caused by calcium deficiency).
