On the bottle of Tiger Bloom you can't read Calcium listed in the components list , but under the list just after the less concentrate nutrient aka Zinc 0.05% you can red " Derived from : Calcium Nitrate , ect" . On the bottle the components are listed from the most present to the less present and the nutrients that are not listed with a % are just traces so here you have trace of Calcium Nitrate which means you have NO SUBTENTIAL AMOUNT OF CALCIUM in that bottle 😋
Aslo calcium def is looking like manganese def but calcium excess is different as there is NO rust spot when it is an excess of calcium. Here is a link to see by yourself : https://www.loudclouds.co/plant-nutrient-deficiency-chart/ 😎
Now take a look to the Big Bloom bottle , turn it back and look at the components list , here again no sign of calcium , and please search for Ca3(PO4)2 because it is the Tricalcium Phosphate formula and the Big Bloom is FREE FROM THAT SHIT , no traces of it inside , not even a drop 😒
Now you know that you need to double check any advices to be sure of what you'll do
