First Lager & 3rd AG Brew - Look Right?

This is my third AG brew, and my first lager. (a Munich Helles)

I'm wondering if this looks good so far - the krausen took a day to get going and then built up nicely. But I was expecting it to drop down after 6-7 days. I'm used to Ale fermentation which is very easy to see when it is done working.
I haven't taken a reading since pitching. I wanted to leave it undisturbed as much as possible. I know looking at it is not very definitive, but was hoping some lager experts could advise - "leave it alone until krausen falls off" or "read it and decide".

This puppy will take about another 6 weeks before I can taste the final goods, so I am trying to be careful.

Any advice welcome!

Cheers

I don't even usually even look at my lagers until 10-14 days in primary. By then, the krausen has usually fallen. If I'm doing a diacetyl rest, I'll check the SG to see where I'm at. If I'm at 75% or so finished, I do the diacetyl rest then while the fermenting finishes up.

You may want to wait about 3-4 days and check the sg and see if you're ready for the diacetyl rest.

+1 on yooper's advice. what, by the way, was your mash schedule? did you decoct?

YooperBrew - thanks; reassuring to wait then and not mess with it.

blackwater - yes I did a triple decoction following several books & Kaiser's video. Here's the info:

Edward's Helles Decoction Mash, Triple, Lager Step Time Name Description Step Temp
20 min Acid Rest Add 6.25 qt of water at 113.5 F 105.0 F
25 min Protein Rest Add 3.00 qt of water at 166.5 F 122.0 F
12 min Beta Sacch Decoct 3.20 qt of mash and boil it 146.0 F
15 min Alpha Sacch Decoct 1.64 qt of mash and boil it 155.0 F
5 min Mash Out - Half Mash Decoction Decoct 3.16 qt of mash and boil it 170.0 F

I did have trouble meeting the 170 F at the end. A 5 Gallon MLT just isn't big enough I think... Next time I'm moving to a 10 gallon.

Forgot to post a pic of this Lager.... Very clean and tasty. Though I seem to suck at photographing by beers....
