First off for the pH pen you need to things you can get from the grow store. You need storage solution (assuming you got a good one) and calibration fluid. The pen will stop working if the tip drys out. so you can get a bottle of storage solution at the grow store and one bottle will last forever. The calibration fluid is needed as you should be calibrating regularly. I do it at least every month and whenever things start not making sense. I know what my water should be out of the tap so that's how you know. Some people calibrate weekly but that is overkill.
So Calcium Def is one of those that once it is there it wont get fixed. That part of the leaf is dead. When the new leafs come in and look good you know you have fixed it. Calcium is one you can't over do so just follow the bottles recommendation for a high dose for the next watering and you should be fine. I can't remember how long it takes for calcium def to stop but what you are looking for is new growth to be good and for the spots to stop spreading. Then you can back off to once every 2 weeks and you will be fine. All of that assuming the pH is good.
Silica is a goofy one. In soil it really needs to be there a while and break down for the plant to absorb it. With the bacteria it works faster. I end up using it also as my pH UP when adjusting water so it gets added a bit at a time anyway. That is one I also would add just once every 2 weeks according to the bottles instruction. The plant wont suffer at all without it and if you don't know better you would never see the plant have issues without it. But it really helps make strong stalks that will hold up to heavy buds. It also helps make strong stalks that do well under training. So assuming we get some big buds at the end of this we will want some strong stalks.
lets wait to see them dry out and decide if we need to add VF-11. that tea has a lot of natural fertilizers so you may be good to go. you may just need the Cal Mag and the Silica for the first watering. I rarely but some times even get a little nute burn from it if it unlocks and breaks down stuff in the soil that was sitting there not available.
A good soil blend like what I try to do almost goes the grow without fertilizers.
VF-11 ids great stuff and very well balanced and easy to use so it is good general purpose recovery food. In hydro I use it as the main fert through all of Veg. That plus some Silica and some Cal mag will get me all the way through veg with very nice plants.
