EI dosing question

Can some one who is either using or is familiar with the Estimative Index answer a question for me? I'm dosing my 55 gallon with the following schedule: Sun.- 50% water change 1/2 tsp.KNO3,1/8 tsp.PO4, 1/8 tsp. potassium.Mon.- 10 ml csm+b. Then the same for the rest of the week alternating. My question is should I dose on Sat. or not dose anything, because I see some people dosing and some taking a day off before water change.The tank is 4wpg co2 injected etc. Thanks for the clarification,

Saturday off is cool. I dose the same.
You're on the right track, how do the plants look? are they responding well? that is the main thing to look out for, learn to read the plant's test kit's lie algae and plant do not!

The plants look good, alot better then before I started using the EI. I've been using this for about 4 weeks now and have noticed a huge difference in growth and overall plant health. The only reason I was asking if I should dose on Saturday was because I thought it might interfere with the amounts. I mean that I thought I read that Tom said that the maximum nitrates would be about 20ppm with the weekly resetting, it wouldn't be able to go much higher than that. But if I dosed on Sat. wouldn't that throw off the amounts a little? Unless I misunderstood. Actually I suppose it really doesn't matter all that much because everything is growing very well and the plants seem healthy, so that is really what is important.Thanks for the help,

I have been using the EI for the past four months on my 55 and I couldn't be happier. I cannot speak for Tom but I think one of the beauties of the system is that it really doesn't matter if you do the Saturday dosing or not. In fact, I have actually seen him recommend a variation of EI that calls for a larger "mega" dose just before the water change. If you don't like the idea of dosing macros two days in a row (Saturday & Sunday) you might consider adjusting the midweek schedule to have two days in a row of TE and that way you will be dosing macros on Friday and then again on Sunday.
