So youre saying top dress fert is better than liquid fert in containers? I guess that makes alot more sense then mixing up batches. Would just have to water regularly with the top dress, save some time. Before, I would mix up liquid ferts and hand water my few dozen plants.
Since I am not using any drip lines, would the choice be tropicote or still calcinit because of my slight acidic water?
better? probably not, but it wont make much difference.
calcium nitrate is very hydroscopic. it will absorb so much moisture from the air that it will literally dissolve itself into the soil.
i mentioned the top dres because you could simply broadcast it onto your plant rows, and then till it in lightly with a rake... but if you are growing in containers, you might as well just dissolve it in water.
your tap water acidity has nothing to do with the calcium nitrate. just buy the tropicote unless you need the very high purity stuff making fertilizer concentrates or fertigation.
5.2 ph is not that bad, but you might soil test your container media after fertilizer incorporation to see whats going on. if you still need to bring up the ph, you can get some gypsum dust, or dolomite lime(calcium and magnesium carbonate mostly) and bring it down by incorporating it into the media when you transplant, or just broadcast it onto the top.
keep in mind calcium nitrate will not satisfy all your plants needs... you will need to satisfy all of the other nutrient demands some how... you can do this with another bagged water soluble fertilizer like peters professional ... peat lite special is popular.
or with somethign like osmocote pro which is time released fertilizers + micronutrients. i dont like using CRF's if i can avoide it though.
