How did everyone figure out their dosing regimen?

I have two low tech tanks (8 gallon and 15 gallon) that I need to figure out how to fertilize. How does everyone figure out their schedules? Sigh, here I thought lighting was going to be the most difficult part of this journey from unplanted to planted tanks.

Just started working with planted tanks
8g tank starring Merlin the betta (planted)
15g tall tank containing tetras and corys (planted)

The second link only addresses dosing for a high light, CO2 enriched tank though. Would it be easy to translate the EI concept (which mentions Plantex CSM +B) to flourish excel?

Best advice I can say is watch your plants. If your doing ei slowly reduce individual ferts until u notice deficiency. They sell tests to measure fert levels but watching your plants and observing algae is best.
For example, I have been dosing modified ei for non co2 tank. I just started a plant wall with about 40 different anubias and java ferns and in three days my nitrates bottomed out, as per watching my plants, and so did potassium. Soo, I will be upping them and watching how the plants react.

If in doubt, add more plants!

The Flourish Excel is used as a CO2 substitute in non-CO2 gassed systems and typically dosed at double the daily dosage, in CO2 gassed systems Excel is used as algae control dosed at recommended daily limits. Excel is a source of carbon there are other ferts one need to use when it comes to fertilizing a tank.

I personally am going with a 1/2 dose of the EI scale for my non-CO2 gas tank to begin with, I am currently doing this with the Flourish line and I dose double the Excel. There was a thread here about low light, low tech using a 1/2 dosing modified EI scheduled for these set ups that led me to pick that as my starting point. I'm using Flourish products now but the amount a nutrient calculator gave me to dose those products makes the cost factor a tad harder to swallow even at 1/2 of the EI. I'll be going to dry ferts in the next week or two. Thing is to pick a starting point and adjust from there.

I sort of agree with the comment regarding watching the plants. Plagued by aggressive algae, apparent deficiencies or slow growth? Are the plants root feeders or not? I sort of went every which way in attacking issues in my aquarium. Things are looking great after some process of elimination.

http://calc.petalphile.com/ - has a low light EI calculator. Perhaps someone else will comment if dosing excel with that calculator setting would be sufficient. I used this tool to mix some dry ferts (bought online) with some distilled water to make an easily dosable solution. No matter what bottle I pick up, I have it calculated to dose the same volume of solution. I just need to rotate the days. -- I think that a cheap .1 gram scale, dry ferts, couple jugs of distilled water and some empty containers is a fine investment vs jugs of nutrient supplements that could be store bought.

http://deficiencyfinder.com/ - Got particular deficiency issues? perhaps a tool such as this could help you decide on particular fert to dose if you don't want to go full ei.

I've tried the osmocote+ methods for root feeders. I found that that some osmo wound up coming out of the substrate and threw off my dosing requirements. Next time I'm sticking them as far below the surface as I can possibly reach and I'm not going to try to stick too many down there at one time.

So since you are polling the community...I've got a 55g high tech at the moment. I found that despite dosing I was not seeing the effects I wanted. I went ahead and threw a powerhead into the mix and everything is looking much better. The added flow is helping with both algae prevention and nutrient circulation.
